Executive Summary

Introduction

The Boston Region Metropolitan Planning Organization’s (MPO) five-year capital investment plan, the Federal Fiscal Years (FFYs) 2024–28 Transportation Improvement Program (TIP), is the near-term investment program for the region’s transportation system. Guided by the Boston Region MPO’s vision, goals, and objectives, the TIP prioritizes investments that preserve the current transportation system in a state of good repair, provide safe transportation for all modes, enhance livability, promote equity and sustainability, and improve mobility throughout the region. These investments fund arterial roadway and intersection improvements, maintenance and expansion of the public transit system, bicycle path construction, infrastructure improvements for pedestrians, and major highway reconstruction.

The Boston Region MPO is guided by a 22-member board with representatives of state agencies, regional organizations, and municipalities. Its jurisdiction extends roughly from Boston north to Ipswich, south to Marshfield, and west to municipalities along Interstate 495. Each year, the MPO conducts a process to decide how to spend federal transportation funds for capital projects. The Central Transportation Planning Staff (CTPS), which is the staff to the MPO, manages the TIP development process.

MPO staff coordinates the evaluation of project funding requests, proposes programming of current and new projects based on anticipated funding levels, supports the MPO board in developing a draft TIP document, and facilitates a public review of the draft before the MPO board endorses the final document.

FFYs 2024–28 TIP Investments

The complete TIP program is available in Chapter 3 of this document and online at bostonmpo.org/tip. The TIP tables provide details of how funding is allocated to each programmed project and capital investment program. These tables are organized by federal fiscal year and are grouped by highway and transit programs.

Highway Program

The Highway Program of the TIP funds the priority transportation projects advanced by the Massachusetts Department of Transportation (MassDOT) and the cities and towns within the Boston region. The program is devoted primarily to preserving and modernizing the existing roadway network by reconstructing arterial roadways, resurfacing highways, and replacing bridges.

In Massachusetts, Federal-Aid Highway Program funding is apportioned by MassDOT, which allocates funding to Grant Anticipation Notes (GANs) payments, various statewide programs, and Regional Targets for the state’s MPOs. In the FFYs 2024–28 TIP, roadway, bridge, and bicycle and pedestrian programs account for nearly $2.4 billion in funding to the Boston region. The Regional Target funding provided to the MPOs may be programmed for projects at the discretion of each MPO, whereas MassDOT has discretion to propose its recommended projects for statewide programs, such as those related to bridge repairs and interstate highway maintenance.

Transit Program

The Transit Program of the TIP provides funding for projects and programs that address the capital needs prioritized by the three transit authorities in the region: the Massachusetts Bay Transportation Authority (MBTA), the Cape Ann Transportation Authority (CATA), and the MetroWest Regional Transit Authority (MWRTA). The Transit Program is predominantly dedicated to achieving and maintaining a state of good repair for all assets throughout the transit system.

The FFYs 2024–28 TIP includes $4.05 billion in transit investments by the transit authorities that will support state of good repair, modernize transit systems, and increase access to transit. Additionally, beginning in FFY 2025, the MPO will allocate $6.5 million of its annual Regional Target funds to its new Transit Modernization investment program. This program aims to build on the investments made through the Transit Program by using a portion of Highway Program funding to fulfill unmet transit project needs in the region. The MPO has already begun to fund discrete projects through this program prior to FFY 2025 based on a surplus of available funding in FFY 2024, as detailed below.

Regional Target Program Details

During FFYs 2024–28, the Boston Region MPO plans to fund 58 projects with its Regional Target funding. In total, 21 new projects were added to the MPO’s Regional Target Program during this TIP cycle. Details on these projects are available in Table ES-1.

Signed into law on November 15, 2021, the Bipartisan Infrastructure Law (BIL) is the five-year federal funding authorization for transportation projects and programs, replacing the Fixing America’s Surface Transportation (FAST) Act as the primary governing legislation for the TIP process. The BIL increased the amount of Regional Target funding available to the Boston Region MPO for the development of the FFYs 2024–28 TIP by approximately 20 percent from the funding levels in TIPs under the FAST Act, the last of which was the FFYs 2022–26 TIP.

The majority of the funding available for allocation by the MPO during the FFYs 2024–28 TIP cycle was in the fifth and final year of the TIP, FFY 2028. However, changes in project readiness for some projects created funding surpluses in the early years of the TIP, FFYs 2024 and 2025, and in FFY 2027. These surpluses were driven by programming delays for several projects already funded by the MPO. This dynamic led to a funding surplus in excess of $66.5 million in FFYs 2024 and 2025 and total funding availability of $202 million across all years of the TIP.

The MPO did not have any currently funded Regional Target projects that could be accelerated to make use of these funds, so the MPO worked with MassDOT and the MBTA to identify projects that could be funded in these fiscal years. Jointly, MassDOT and the MBTA brought more than a dozen projects to the MPO for consideration, from which the MPO selected four projects for funding in FFYs 2024 and 2025:

• Columbus Avenue Bus Lanes Phase II     
• Rail Transformation Early Action Items—Reading Station and Wilbur Interlocking    
• Jackson Square Station Accessibility Improvements
• Chelsea—Targeted Safety Improvements and Related Work on Broadway, from Williams Street to City Hall Avenue

The MPO also selected a MassDOT project for funding in FFY 2027:

• Everett—Targeted Multi-Modal and Safety Improvements on Route 16

These projects were not formally evaluated using the MPO’s project selection criteria prior to the MPO making draft funding decisions, as MPO staff did not have sufficient time to score the projects prior to the deadline for MPO decision-making. Despite not being scored, the projects generally align well with many of the MPO’s goals, including enhancing bicycle and pedestrian safety and access, and expanding the accessibility of and maintaining a state of good repair for the region’s transit system and critical roadways. Scoring information will be included for these projects when available.

Several other key decisions were made by the MPO in the drafting of the FFYs 2024–28 Regional Target Program, including the following:

• The MPO introduced a Bikeshare Support Set-Aside line item to fund capital repair and improvement projects for Bikeshare initiatives in the region starting in FFY 2025. The project is funded at $1 million per year in FFYs 2025 and 2026 and $2 million per year in FFYs 2027 and 2028.
• In FFY 2025 the MPO allocated $4 million to fund a pilot initiative that would provide MPO funding support for communities to design projects and offer additional resources to communities earlier in a project’s lifecycle.
• The programmed amount of Project 607981, Somerville—McGrath Boulevard Construction, in FFY 2027 was increased by $15 million to accelerate the project’s timeline.
• The $6.4 million contribution by the MPO to the MBTA’s Forest Hills Station Improvement Project in FFY 2024 was removed due to the lack of funding availability from other contributors.

Figure ES-1 shows how the Regional Target funding for FFYs 2024–28 is distributed across the MPO’s investment programs. As the chart shows, the Boston Region MPO’s Regional Target Program is devoted primarily to enhancing mobility and safety for all travel modes through significant investments in Complete Streets projects. A large portion of the MPO’s funding also supports the modernization of key regional roadways and transit infrastructure through investments in Major Infrastructure and Transit Modernization projects. The MPO also elected to leave approximately $31.9 million unprogrammed, preferring to retain these funds for use in future TIP cycles in support of a more flexible overall program in the coming fiscal years.

In addition to the distribution of funding across the MPO’s investment programs listed above, Table ES-2 further details the number of projects and the allocation of funds across each program in the FFYs 2024–28 TIP. As noted in Figure ES-1, the MPO has programmed more than 95 percent of its available funding over five years. More details about every project funded through the MPO’s Regional Target Program are available in Chapter 3.

When making decisions about which projects to fund, the MPO considers how the allocation of funds to each investment program compares to the funding goals outlined in the MPO’s current Long-Range Transportation Plan (LRTP), Destination 2040. The funding goals for investment programs set forth in the LRTP reflect the types of projects the MPO seeks to fund to help it achieve its goals and objectives for the region, from enhancing safety for all users to promoting mobility and accessibility across the region. More information on the MPO’s goals and objectives is available in Chapter 1, and a comparison between LRTP investment program goals and program funding levels in the FFYs 2024–28 TIP is shown in Figure ES-2.

The investments made in the FFYs 2024–28 TIP will be implemented in 38 cities and towns throughout the Boston region, ranging from dense inner core communities to developing suburbs further from the urban center. Figure ES-3 illustrates the distribution of Regional Target funding among the eight subregions within the Boston Region MPO’s jurisdiction, as defined by the Metropolitan Area Planning Council (MAPC). This figure also shows how the distribution of funds compares to key metrics for measuring the need for funding by subregion, including the percent of regional population, employment, and Federal-Aid roadway miles within each subregion.

Financing The FFYs 2024–28 TIP

Highway Program

The TIP Highway Program was developed with the assumption that federal funding for the state would range between $709 million and $865 million annually over the next five years. These amounts include the funds that would be set aside initially by MassDOT as payments for the Accelerated Bridge Program and exclude required matching funds. The funding levels for the FFYs 2024–28 TIP’s Highway Program represent an increase of approximately two percent over those in the FFYs 2023–27 TIP.

The process of deciding how to use this federal funding in the Boston region follows several steps. First, MassDOT reserves funding for GANs debt service payments for the Accelerated Bridge Program; annual GANs payments range between $89 million and $134 million annually over the first three years of this TIP. GANs payments for the Accelerated Bridge Program are expected to conclude in FFY 2026.

The remaining Federal-Aid Highway Program funds are budgeted to support state and regional (i.e., MPO) priorities. In the FFYs 2024–28 TIP, $1.07 billion to $1.15 billion annually was available for programming statewide, including both federal dollars and the local match. MassDOT customarily provides the local match (which can also be provided by other entities); thus, projects are typically funded with 80 percent federal dollars and 20 percent state dollars, depending on the funding program. Costs for project design are borne by the proponent of the project.

Next, MassDOT allocates funding across the following funding categories:

• Reliability Investments: These programs include the Bridge Program—comprising inspections, systematic maintenance, and National Highway System (NHS) and non-NHS improvements—the Pavement Program, the Roadway Improvements Program, and the Safety Improvements Program.
• Modernization Investments: These programs include the Americans with Disabilities Act (ADA) Retrofit Program, the Intersection Improvement Program, the Intelligent Transportation Systems (ITS) Program, and the Roadway Reconstruction Program.
• Expansion Investments: These programs include the Bicycle and Pedestrian Program and transit network expansions.

Finally, once these needs have been satisfied, MassDOT allocates the remaining funding among the state’s 13 MPOs for programming. This discretionary funding for MPOs is suballocated by formula to determine the Regional Target amounts. The Boston Region MPO receives the largest portion of MPO funding in the state, with approximately 43 percent of Massachusetts’ Regional Target funds allocated to the region. MassDOT develops these targets in consultation with the Massachusetts Association of Regional Planning Agencies (MARPA). This TIP was programmed with the assumption that the Boston Region MPO will have between $129 million and $158 million annually for Regional Target amounts, which consist of federal funding and state funding for the local match.

Each MPO may decide how to prioritize its Regional Target funding. Given that the Regional Target funding is a subset of the Highway Program, the MPO typically programs the majority of funding for roadway projects; however, the MPO has flexed portions of its highway funding to the Transit Program for transit expansion projects and through its Transit Modernization and Community Connections Programs. The TIP Highway Program details the projects that will receive Regional Target funding from the Boston Region MPO and statewide infrastructure projects within the Boston region. Details on these investments are outlined in Chapter 3.

Transit Program

The Federal Transit Administration (FTA) allocates the funds programmed in the TIP Transit Program according to formula. The three regional transit authorities in the Boston Region MPO area that are recipients of these funds are the MBTA, CATA, and MWRTA. The MBTA, with its extensive transit program and infrastructure, is the recipient of the preponderance of the region’s federal transit funds.

As the current federal transportation legislation, the BIL allocates funding to transit projects through the following formula programs:

• Section 5307 (Urbanized Area Formula Grants): Provides grants to urbanized areas to support public transportation based on levels of transit service, population, and other factors
• Section 5337 (Fixed Guideway/Bus): Seeks to maintain public transportation systems in a state of good repair through replacement and rehabilitation capital projects
• Section 5309 (Fixed Guideway Capital Investment Grants): Provides grants for new and expanded rail, bus rapid transit, and ferry systems that reflect local priorities to improve transportation options in key corridors
• Section 5339 (Bus and Bus Facilities): Provides funding to replace, rehabilitate, and purchase buses and related equipment, and to construct bus-related facilities
• Section 5310 (Enhanced Mobility of Seniors and Individuals with Disabilities): Provides funding to support transportation to meet the special needs of older adults and persons with disabilities

The TIP Development Process

Overview

When determining which projects to fund through the Regional Target funding process, MPO members collaborate with municipalities, state agencies, members of the public, advocacy groups, and other stakeholders. The MPO board uses evaluation criteria in its project selection process to help identify and prioritize projects that advance progress on the MPO’s six goal areas:

• Safety
• System Preservation and Modernization
• Capacity Management and Mobility
• Clean Air/Sustainable Communities
• Transportation Equity
• Economic Vitality

Additionally, the MPO has established investment programs, which are designed to direct Regional Target funding towards MPO priority areas over the next 20 years, to help meet these goals. The investment programs are as follows:

• Intersection Improvements
• Complete Streets
• Major Infrastructure
• Bicycle Network and Pedestrian Connections
• Community Connections
• Transit Modernization

Projects that the MPO selects to receive Regional Target funding through the TIP development process are included in one of the six investment programs listed above. More information on the MPO’s investment programs is available in Chapter 2.

The MPO incorporates performance-based planning and programming (PBPP) practices into its TIP development and other processes. These practices are designed to help direct MPO funds towards achieving specific outcomes for the transportation system. MPO investments directly relate to the PBPP framework and further the MPO’s goals and performance targets.  With the development of the FFYs 2024-28 TIP, the MPO leveraged funding availability across all fiscal years to program new projects to address transit system reliability, traffic safety for all users, NHS bridge condition, and other priorities. The MPO will continue to closely link its performance targets, investment decisions, and monitoring and evaluation activities. More information on PBPP is available in Chapter 4 and Appendix A (Table A-2).

Outreach and Data Collection

The outreach process begins early in the federal fiscal year. Cities and towns designate TIP contacts and begin developing a list of priority projects to be considered for federal funding, and the MPO staff asks the staff of cities and towns in the region to identify their priority projects. MPO staff compiles the project funding requests into a Universe of Projects, which is a list of all Bicycle Network and Pedestrian Connections, Complete Streets, Intersection Improvements, and Major Infrastructure projects identified as potential candidates to receive funding through the TIP.

Certain types of projects are not listed in the Universe at this time. Projects that would be candidates for funding from the MPO’s Community Connections Program are not included because all projects that apply for this program’s discrete application process are considered for funding. Also, Transit Modernization projects are not listed because the project intake process for this program is being developed. During the development of the FFYs 2024-28 TIP, the MPO engaged transit stakeholders to provide projects to utilize funding availability in FFYs 2024 and 2025, an exception to the process but a key step towards formalizing an intake strategy for the next FFYs 2025–29 TIP.

The Universe includes projects at varying levels of readiness, from those with significant engineering and design work complete to those still early in the conceptual or planning stage. MPO staff collects data on each project in the Universe so that the projects may be evaluated.

Project Evaluation

MPO staff evaluates projects based on how well they address the MPO’s goals. For MPO staff to conduct a complete project evaluation, Bicycle Network and Pedestrian Connections, Complete Streets, Intersection Improvements, and Major Infrastructure projects must have a functional design report or the project plans must include the level of detail defined in a functional design report, a threshold typically reached when a project nears the 25 percent design stage. To complete an evaluation for projects under consideration through the MPO’s Community Connections Program, project proponents must submit a completed application to MPO staff.

In response to significant cost increases in recent TIP cycles for projects already programmed for funding, the MPO board created a committee in the wake of the FFYs 2022–26 TIP cycle to further explore the causes of project cost increases and devise MPO policy changes to support more reliable project delivery. The TIP Project Cost Ad Hoc Committee began its work in June 2021 and advanced a set of policy recommendations to the full MPO board in September 2021. These changes were formally adopted by the MPO on November 4, 2021, and were in effect for the development of the FFYs 2024–28 TIP.

Among other changes, the MPO elected to codify its policy of requiring that project proponents submit 25 percent designs and obtain an updated cost estimate for their projects prior to being programmed in the TIP. While this new policy was formally in effect for the FFYs 2024–28 TIP cycle, the MPO desired to keep this threshold flexible in its first year of implementation, given that the policy was not adopted until after the start of TIP development.

The evaluation results for all projects are presented to the MPO board members for their consideration for programming in the TIP. Draft scores are shared directly with project proponents, at which point proponents are encouraged to review the scores and provide feedback so that MPO staff may make any warranted adjustments to arrive at accurate final results. Once proponents review their scores, final scoring results are posted on the MPO’s website where MPO members, municipal officials, and members of the public may review them.

TIP Readiness Day

An important step toward TIP programming takes place midway through the TIP development cycle at a meeting—referred to as TIP Readiness Day—that both MassDOT and MPO staff attend. At this meeting, MassDOT project managers provide updates about cost and schedule changes related to currently programmed projects. These cost and schedule changes must be taken into account as MPO staff helps the MPO board consider updates to the already programmed years of the TIP, as well as the addition of new projects in the outermost year of the TIP.

Among the other new policies advanced by the TIP Project Cost Ad Hoc Committee, the MPO board adopted a policy requiring proponents of projects that experienced a cost increase of 25 percent or more (for projects costing less than $10 million) or $2.5 million or more (for projects costing more than $10 million) to present to the MPO board on the reasons for these cost increases. The MPO would then compare these projects—at the new costs—to other projects and consider this cost-effectiveness evaluation when deciding whether or not to fund the projects at the higher costs. These cost changes are most often revealed through conversations between MassDOT staff and MPO staff during TIP Readiness Day, making this new policy especially relevant at this stage of TIP development.

Staff Recommendation and Draft TIP

Using the evaluation results and information about project readiness (i.e., the extent to which a project is fully designed and ready for construction), MPO staff prepares a recommendation or a series of programming scenarios for how to program the Regional Target funding in the TIP. Other considerations, such as whether a project was included in the LRTP, addresses an identified transportation need, or promotes distribution of transportation investments across the region, are also incorporated into these programming scenarios. The staff recommendation is always financially constrained—meaning, subject to available funding. There was approximately $698 million of Regional Target funding available to the Boston Region MPO for FFYs 2024–28. In this TIP cycle, the MPO board members discussed several scenarios for the Regional Target Program for highway projects and selected a preferred program in March 2023.

In addition to prioritizing the Regional Target funding, the MPO board reviews and endorses the statewide highway program that MassDOT recommends for programming. The board also reviews and endorses programming of funds for the MBTA’s, CATA’s, and MWRTA’s transit capital programs.

Approving The TIP

After selecting a preferred programming scenario, usually in late March, the MPO board votes to release the draft TIP for a 21-day public review period. The comment period typically begins in late April or early May, and during this time the MPO invites members of the public, municipal officials, and other stakeholders in the Boston region to review the proposed program and submit feedback. During the public review period, MPO staff hosts public meetings to discuss the draft TIP document and elicit additional comments.

After the public review period ends, the MPO board reviews all municipal and public comments and may change elements of the document or its programming. The MPO board then endorses the TIP and submits it to the Federal Highway Administration (FHWA) and the Federal Transit Administration (FTA) for approval. MassDOT incorporates the MPO-endorsed TIP into the State Transportation Improvement Program (STIP). The FHWA, FTA, and United States Environmental Protection Agency review the STIP for certification by September 30, the close of the federal fiscal year.

Updates To The TIP

Even after the TIP has been finalized, administrative modifications, amendments, and adjustments often must be introduced because of changes in project schedules, project costs, funding sources, or available revenues. This may necessitate reprogramming a project in a different funding year or programming additional funds for a project.

Notices of administrative modifications and amendments are posted on the MPO’s website. If an amendment is necessary, the MPO notifies affected municipalities, stakeholders, and members of the public via email. The MPO typically holds a 21-day public review period before taking final action on an amendment. In extraordinary circumstances, the MPO may vote to shorten the public comment period to a minimum of 15 days. Administrative modifications and adjustments are minor and usually do not warrant a public review period.

Chapter 1: 3C Transportation Planning and the Boston Region Metropolitan Planning Organization

Chapter 1
3C Transportation Planning and the Boston Region Metropolitan Planning Organization

Decisions about how to allocate transportation funds in a metropolitan area are guided by information and ideas gathered from a broad group of people, including elected officials, municipal planners and engineers, transportation advocates, and interested residents. Metropolitan planning organizations (MPO) are the bodies responsible for providing a forum for this decision-making process. Each metropolitan area in the United States with a population of 50,000 or more, also known as an urbanized area, is required by federal legislation to establish an MPO, which decides how to spend federal transportation funds for capital projects and planning studies for the area.

THE TRANSPORTATION PLANNING PROCESS

The federal government regulates the funding, planning, and operation of the surface transportation system through the federal transportation program, which was enacted into law through Titles 23 and 49 of the United States Code. Section 134 of Title 23 of the Federal Aid Highway Act, as amended, and Section 5303 of Title 49 of the Federal Transit Act, as amended, require that urbanized areas conduct a transportation planning process, resulting in plans and programs consistent with the planning objectives of the metropolitan area, in order to be eligible for federal funds.

The most recent reauthorization of the federal surface transportation law is the Bipartisan Infrastructure Law (BIL), which has succeeded the Fixing America’s Surface Transportation (FAST) Act. The BIL sets policies related to metropolitan transportation planning, and requires that all MPOs carry out a continuing, comprehensive, and cooperative (3C) transportation planning process.

3C Transportation Planning

The Boston Region MPO is responsible for carrying out the 3C planning process in the Boston region. The MPO has established the following objectives for the process:

• Identify transportation problems and develop possible solutions
• Ensure that decision-making balances short- and long-range considerations and adequately reflects the range of possible future scenarios, options, and consequences
• Represent both regional and local considerations, and both transportation and non-transportation objectives and impacts, in the analysis of project issues
• Assist implementing agencies in effecting timely policy and project decisions with adequate consideration of environmental, social, fiscal, and economic impacts, and with adequate opportunity for participation by other agencies, local governments, and the public
• Help implementing agencies prioritize transportation activities in a manner consistent with the region’s needs and resources

Municipalities in the Boston Region

The MPO’s board comprises 22 voting members. Several state agencies, regional organizations, and the City of Boston are permanent voting members, while 12 municipalities are elected as voting members for three-year terms. Eight municipal members represent each of the eight subregions of the Boston region, and there are four at-large municipal seats. The Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) participate on the MPO board as advisory (nonvoting) members. More details about the MPO’s permanent members can be found in Appendix F.

MPO Central Vision Statement

The following paragraph is the MPO’s central vision statement, as adopted in Destination 2040, the MPO’s current Long-Range Transportation Plan (LRTP), which was adopted in August 2019.

The Boston Region MPO envisions a modern, well-maintained transportation system that supports a sustainable, healthy, livable, and economically vibrant region. To achieve this vision, the transportation system must be safe and resilient; incorporate emerging technologies; and provide equitable access, excellent mobility, and varied transportation options.

This vision statement takes into consideration the significant public input received during the drafting of the Needs Assessment for Destination 2040. This statement also reflects the MPO’s desire to emphasize the maintenance and resilience of the transportation system while supporting the MPO’s six core goals: Safety, System Preservation and Modernization, Capacity Management and Mobility, Clean Air and Sustainable Communities, Transportation Equity, and Economic Vitality. More information on the MPO’s vision, goals, and objectives for the transportation system is available in Figure 1-3.

The Boston Region MPO is in the process of developing Destination 2050, its next LRTP, which is expected to be completed in the summer of 2023. The updated vision, goals, and objectives created as part of Destination 2050 will not only guide the recommendations included in that plan, but also the development of future MPO Transportation Improvement Programs (TIP) and LRTPs. It was also considered when developing this UPWP. The following paragraph is the MPO’s vision statement as approved in February 2023.

The Boston Region Metropolitan Planning Organization envisions an equitable, pollution-free, and modern regional transportation system that gets people to their destinations safely, easily, and reliably, and that supports an inclusive, resilient, healthy, and economically vibrant Boston region.

Certification Documents

As part of its 3C process, the Boston Region MPO annually produces the TIP and the Unified Planning Work Program (UPWP). These documents, along with the quadrennial LRTP, are referred to as certification documents and are required for the federal government to certify the MPO’s planning process. This federal certification is a prerequisite for the MPO to receive federal transportation funds. In addition to the requirement to produce the LRTP, TIP, and UPWP, the MPO must establish and conduct an inclusive public participation process, and maintain transportation models and data resources to support air quality conformity determinations and long- and short-range planning work and initiatives.

The following is a summary of each of the certification documents.

• The LRTP guides decision-making on investments that will be made in the Boston region’s transportation system over the next two decades. It defines an overarching vision of the future of transportation in the region, establishes goals and objectives that will lead to achieving that vision, and allocates projected revenue to transportation projects and programs consistent with established goals and objectives. The Boston Region MPO produces an LRTP every four years. Destination 2040, the current LRTP, was endorsed by the MPO board in August 2019 and went into effect on October 1, 2019. Figure 1-3 shows the MPO’s goals and objectives as adopted by the MPO board in Destination 2040. As previously mentioned, the MPO is developing its next LRTP, Destination 2050. The new plan is expected to be endorsed by the MPO in summer 2023 and to go into effect October 1, 2023.
• The TIP is a multiyear, multimodal program of transportation improvements that is consistent with the LRTP. It describes and prioritizes transportation projects that are expected to be implemented during a five-year period. The types of transportation projects funded include major highway reconstruction and maintenance, arterial and intersection improvements, public transit expansion and maintenance, bicycle paths and facilities, improvements for pedestrians, and first- and last-mile connections to transit or other key destinations. The TIP contains a financial plan that shows the revenue sources, current or proposed, for each project. The TIP serves as the implementation arm of the MPO’s LRTP, and the Boston Region MPO updates the TIP annually. An MPO-endorsed TIP is incorporated into the State Transportation Improvement Program (STIP) for submission to the FHWA, FTA, United States Environmental Protection Agency, and the Massachusetts Department of Environmental Protection for approval. The Capital Investment Plan is a Massachusetts Department of Transportation (MassDOT) document that reflects all capital expenditures over a five year period, and includes STIP, and, by extension, TIP investments.
• The UPWP contains information about transportation planning studies that will be conducted by MPO staff during the course of a federal fiscal year, which runs from October 1 through September 30. The UPWP describes all of the supportive planning activities undertaken by the MPO staff, including data resources management, preparation of the federally required certification documents, and ongoing regional transportation planning assistance. The UPWP, produced annually, is often a means to study transportation projects and alternatives before advancing to further design, construction, and possible future programming through the TIP. The studies and work products programmed for funding through the UPWP are integrally related to other planning initiatives conducted by the Boston Region MPO, MassDOT, the Massachusetts Bay Transportation Authority, the Massachusetts Port Authority, the Metropolitan Area Planning Council, and municipalities in the Boston region.

Chapter 2: The TIP Process

INTRODUCTION TO THE TIP PROCESS

Transportation improvements are part of the solution to many critical regional, state, national, and even global problems, such as traffic congestion, air pollution, fatalities and injuries on roadways, climate change, and environmental injustice. Therefore, one of the most important decisions a metropolitan planning organization (MPO) faces is deciding how to allocate limited funds for transportation projects and programs. Because there is not nearly enough funding available for all of the necessary and worthy projects that would address these problems, an MPO’s investment choices must be guided by policies that help identify the most viable and effective solutions.

The Boston Region MPO is guided by the policies in its Long-Range Transportation Plan (LRTP) and the MPO develops a Transportation Improvement Program (TIP) to prioritize the expenditure of federal funds on transportation projects. The MPO staff manages the development of both plans.

During the annual development process for the TIP, the MPO staff supports the MPO board by evaluating project funding requests from municipalities and state transportation agencies. The staff propose a range of alternative scenarios for the programming of new and ongoing projects, based on anticipated yearly funding levels, and work with the board to create a draft TIP document. The staff also facilitates a public involvement process that affords the public an opportunity to comment on proposed projects and review the draft TIP before the MPO board endorses the final document.

FUNDING the TIP

Federal Funding Framework

The first step in allocating federal transportation funds is the passage by the United States Congress of a multi-year act that establishes a maximum level of federal transportation funding per federal fiscal year (FFY). The establishment of this level of funding is referred to as an authorization. The most recent authorization act, the Bipartisan Infrastructure Law (BIL), was signed into law on November 15, 2021. The BIL governed the development of the FFYs 2024–28 TIP, including by establishing new formula funding levels, creating new and reauthorizing existing discretionary grant programs, and setting policy priorities. (More information on the impacts of the BIL on the development of the FFYs 2024–28 TIP is available throughout this report, with specific guidance on new BIL Planning Emphasis Areas available in Appendix E.)

After the authorization level has been established, the United States Department of Transportation annually allocates funding among the states according to various federal formulas. This allocation is referred to as an apportionment. The annual apportionment rarely represents the actual amount of federal funds that are ultimately committed to a state because of federally imposed limitations on spending in a given fiscal year, referred to as the obligation authority. In Massachusetts, TIPs are developed based on the estimated obligation authority.

Federal Highway Program

The TIP Highway Program was developed with the assumption that federal funding for the state would range between $709 million and $865 million annually over the next five years. These amounts include the funds that would be set aside initially by MassDOT as payments for the Accelerated Bridge Program and exclude required matching funds. The funding levels for the FFYs 2024–28 TIP’s Highway Program represent an increase of approximately two percent over those in the FFYs 2023–27 TIP.

The process of deciding how to use this federal funding in the Boston region follows several steps. First, MassDOT reserves funding for GANs debt service payments for the Accelerated Bridge Program; annual GANs payments range between $89 million and $134 million annually over the first three years of this TIP. GANs payments for the Accelerated Bridge Program are expected to conclude in FFY 2026.

The remaining Federal-Aid Highway Program funds are budgeted to support state and regional (i.e., MPO) priorities. In the FFYs 2024–28 TIP, $1.07 billion to $1.15 billion annually was available for programming statewide, including both federal dollars and the local match. MassDOT customarily provides the local match (which can also be provided by other entities); thus, projects are typically funded with 80 percent federal dollars and 20 percent state dollars, depending on the funding program. Costs for project design are borne by the proponent of the project.

Regional Targets

The Regional Targets are discretionary funds for MPOs, sub-allocated by formula to each metropolitan planning region. The Boston Region MPO receives about 43 percent of the total funds available statewide for Regional Targets. MassDOT developed the target formula for determining this distribution of funds in consultation with the Massachusetts Association of Regional Planning Agencies (MARPA).

Each MPO in the state can decide how to prioritize its Regional Target funding. Given that the Regional Target funding originates from the Federal-Aid Highway Program, the Boston Region MPO board typically programs the majority of its target funding on roadway projects; however, the MPO board has flexed portions of its TIP Highway Program funding to the TIP’s Transit Program, most notably when the MPO board provided funding in support of the Green Line Extension transit expansion project.

Additionally, this FFYs 2024–28 TIP includes an annual allotment of funding to the MPO’s Transit Modernization Program beginning in FFY 2025. This represents the MPO’s first formalized effort to flex Federal-Aid Highway funds to transit projects on a yearly basis, an affirmation of the regional goals to support multimodal transportation options in a meaningful way. More information on the MPO’s investment strategy is discussed later in this chapter.

During the next five years, the Boston Region MPO’s total Regional Target funding will be approximately $697 million, an average of $139.4 million per year. As with the overall increase in funding for the Highway Program from the BIL, the MPO’s Regional Target funds increased nearly nine percent per year in the FFYs 2024–28 TIP relative to the levels planned for in the development of the FFYs 2023–27 TIP. The increase in funding was driven by elevated target funding in FFY 2027 and 2028 resulting from the absence of GANs payments. Funding levels in FFYs 2024 through 2026 remain unchanged from the previous TIP. To decide how to spend its Regional Target funding, the MPO engages its 97 cities and towns in an annual TIP development process.

Federal Highway Administration Programs

The Federal-Aid Highway Program dollars discussed in this chapter are delivered through several Federal Highway Administration (FHWA) funding programs, each of which has unique requirements. Table 2-1 lists the programs in the BIL that fund projects in the FFYs 2024–28 TIP.

Federal Transit Program

Federal aid for public transit authorities is allocated by formula to urbanized areas (UZAs). MassDOT is the recipient of this federal aid in the Boston MA-NH-RI UZA. In UZAs with populations greater than 200,000, such as the Boston MA-NH-RI UZA, the distribution formula factors in passenger-miles traveled, population density, and other factors associated with each transit provider. The three regional transit authorities (RTAs) in the Boston Region MPO area are the Massachusetts Bay Transportation Authority (MBTA), MetroWest Regional Transit Authority (MWRTA), and Cape Ann Transportation Authority (CATA). The MBTA, with its extensive transit program and infrastructure, is the recipient of the preponderance of federal transit funds in the region.

The Federal Transit Administration (FTA) distributes funding to transit agencies through several different programs. As previously noted, the MPO also flexes some of its FHWA funding to FTA to support transit investments. Table 2-2 shows FTA programs in the BIL that support transit investments in the FFYs 2024–28 TIP.

INVESTMENT FRAMEWORKS

MPO Investment Framework

As mentioned previously, each MPO in the state can decide how to prioritize the Regional Target funding it receives through the processes established by FHWA and MassDOT. The Boston Region MPO’s LRTP defines the investment framework that informs the specific investment decisions made in the TIP by establishing

• the MPO’s transportation vision, goals, and objectives, which shape the MPO’s project evaluation criteria;
• MPO investment programs; and
• other guidelines that help the MPO determine how to allocate funding across its investment programs.

MPO Goals and Objectives

The MPO’s goals and objectives provide the foundation for the evaluation criteria the MPO board uses when selecting transportation projects to be funded with Regional Target dollars. MPO staff compares candidate projects’ characteristics to these criteria to evaluate whether individual projects can help the MPO advance its various goals. The criteria used to select projects for this TIP are based on the MPO’s goals and objectives, adopted as part of Destination 2040, which is the LRTP the MPO endorsed in August 2019. These goals and objectives are listed in Chapter 1.

MPO Investment Programs

In Destination 2040 and the prior LRTP, Charting Progress to 2040, the MPO strengthened the link between its spending and improvements to transportation performance by revising its investment programs to include a broader range of prospective projects. These investment programs focus on specific types of projects that the MPO expects will help achieve its goals and objectives for the transportation system. The MPO created these programs to give municipalities the confidence that if they design these types of projects the MPO will be willing to fund them through the TIP:

• Complete Streets
• Intersection Improvements
• Bicycle Network and Pedestrian Connections
• Major Infrastructure (including highway funds flexed to major transit infrastructure)
• Community Connections
• Transit Modernization

Figure 2-1 provides details about the Destination 2040 investment programs and their relationship to the MPO’s goals. When developing the FFYs 2023–27 TIP, the MPO allocated its Regional Target dollars to these investment programs by assigning them to projects that meet the investment programs’ criteria.

Figure 2-1
Destination 2040 Investment Programs

The MPO has taken a clear stance that investing in transit is central to improving the region’s broader transportation system. Created in Destination 2040, the Transit Modernization Program represents a significant shift in the MPO’s investment strategy, as funding will be allocated to transit projects on an annual basis beginning in FFY 2025. In prior years, the MPO only funded transit projects on a one-off basis when funding was requested for specific projects in the region.

By creating the programming infrastructure to flex Regional Target highway funds to transit projects annually, the Boston Region MPO has established itself as a leader among MPOs nationally by crafting an investment strategy that is truly multimodal. During the development of Destination 2050, the next LRTP to be released in 2023, staff proposed a broadening of the Transit Modernization Program into a Transit Transformation Program starting in FFY 2029, in response to feedback from stakeholders at the MBTA and RTAs.^2-1   

The MPO funded multiple Transit Modernization projects in FFY 2024 and FFY 2025 to make use of funding surpluses. The MPO has also continued to reserve funding in the amount of $6.5 million in each fiscal year beginning in FFY 2025 for future allocation. The MPO will continue to work with municipalities and transit providers in the region to identify transit needs and determine the most effective use of this funding as this program commences with the FFYs 2025–2029 TIP. As with the Transit Modernization program, the MPO will continue to work with municipalities to develop and fund projects through the Complete Streets investment program. In Destination 2040, the MPO added dedicated bus lanes and climate resiliency measures to the types of projects supported by this program.

The MPO decided to increase the funding allocated to the Community Connections Program from $2 million to $2.5 million annually beginning in FFY 2023, as the MPO’s overall Regional Target funding increased with the passage of the Bipartisan Infrastructure Law in November 2021. In this FFYs 2024–28 TIP, the MPO built on the success of the first three rounds of the Community Connections Program, funding nine additional projects on top of the 25 projects funded in the previous three TIP cycles. A tenth line item for a Bikeshare Support Set-Aside was also added, which set aside $1 million in funding for Bikeshare in FFYs 2025 and 2026 and $2 million in FFYs 2026 and 2027. Funding for the Community Connections Program continues to be reserved in FFYs 2025–28 for allocation in future TIP cycles.

More information on the projects selected for funding in each of the MPO’s investment programs can be found in Chapter 3.

Other Funding Guidelines

When creating investment program guidelines for Destination 2040, the MPO elected to decrease the amount of funding allocated to large-scale projects that would be included in its Major Infrastructure Program in order to focus a larger percentage of funding on lower cost, operations-and-maintenance projects. Such a funding mix will help the MPO address its goals and provide more opportunities for the MPO to distribute federal transportation dollars to projects throughout the region, as opposed to concentrating it on a few large-scale projects.

Early in the development of the FFYs 2022–26 TIP, the MPO reassessed its definition of Major Infrastructure projects, adopting a new definition through sequential votes on August 20, 2020, and October 1, 2020. This revised definition carried through to the development of the FFYs 2023–27 TIP and persists in the FFYs 2024-28 TIP. The MPO previously defined Major Infrastructure projects as those that cost more than $20 million or that add capacity to the transportation network. The MPO’s revised definition classifies Major Infrastructure projects as follows:

• Roadway projects:
• Capital projects that improve facilities that are important to regional travel, which include
• interstate highways
• principal arterial freeways and expressways
• all sections of roadways classified as principal arterial “other” that have fully or partially controlled access
• Projects that cost $50 million or more
• Transit projects:
• Capital projects that add new connections to or extend the rail or fixed guideway transit network
• Projects that cost $50 million or more

Under the MPO’s prior Major Infrastructure definition, the relatively low-cost threshold caused several large-scale Complete Streets projects to be classified as Major Infrastructure projects although they were local in nature. The changes outlined above are intended to focus the Major Infrastructure investment program on those projects that are of significant scale or that are truly important for the broader region. This allows the MPO to better compare projects when conducting project evaluations. Because the MPO considers the five-year distribution of TIP funds across its investment programs relative to the goals set forth in the LRTP (as shown in Figure 2-2), properly categorizing projects is a critical component of the MPO’s decision-making process. Funding allocation goals like these are some of the LRTP-based guidelines the MPO employs to ensure limited Regional Target funding is programmed in ways that best achieve the MPO’s goals for transportation in the region. As the MPO continues the development of its next LRTP, Destination 2050, it will assess the efficacy of each of its six investment programs to ensure these programs are structured to best support progress on the MPO’s goals and objectives for the region.

Figure 2-2
Destination 2040 Funding Goals by MPO Investment Program

The MPO requires that project proponents submit 25 percent designs and obtain an updated cost estimate for their project prior to being programmed in the TIP. This standard was set by the MPO as part of a multi-pronged effort to reduce the prevalence of cost increases for projects that have already been selected for funding in the TIP.

MassDOT and Transit Agency Investment Frameworks

MassDOT and the MBTA each update their rolling five-year Capital Investment Plans (CIP) on an annual basis. MassDOT’s CIP identifies priority roadway,  bridge, and statewide infrastructure projects for the five MassDOT divisions and includes funding for specific transit projects such as the South Coast Rail. The MBTA’s CIP outlines the agency’s five-year investment strategy for transit projects in its service area. Both CIP processes use a similar framework that prioritizes funding according to statewide strategic goals for the transportation system. Reliability is the top priority for MassDOT and the MBTA, followed by modernization and then expansion. Both agencies have created investment programs for their respective CIPs that relate to these strategic goals and allocate funding to these programs in ways that emphasize their priority. These goals and investment programs are as follows:

• Reliability: These investments are oriented toward maintaining and improving the overall condition and reliability of the transportation system. They include capital maintenance projects, state-of-good-repair projects, and other asset management and system preservation projects. The MassDOT Highway Division programs in this area include the Bridge Program—including inspections, systematic maintenance, and National Highway System (NHS) and non-NHS improvements—the Pavement Program, the Roadway Improvements Program, and the Safety Improvements Program. MBTA reliability programs include its Revenue Vehicles Program; Track, Signals, and Power Program; Bridge and Tunnel Program; Stations Program; Facilities Program; and Systems Upgrade/Other investments.

• Modernization: These investments enhance the transportation system to make it safer and more accessible and to accommodate growth. These projects address compliance with federal mandates or other statutory requirements for safety and/or accessibility improvements; exceed state-of-good-repair thresholds to substantially modernize existing assets; and provide expanded capacity to accommodate current or anticipated demand on transportation systems. The MassDOT Highway Division programs in this area include the Americans with Disabilities Act (ADA) Retrofit Program, the Intersection Improvement Program, the Intelligent Transportation System (ITS) Program, and the Roadway Reconstruction Program. MBTA programs in this area include the Red and Orange Line Improvements Program, the Commuter Rail Safety and Resiliency Program, the Accessibility Program, the Risk Management and Mitigation Program, the Automated Fare Collection (AFC) Program, the Rail Transformation Program, and the Customer Experience and Technology Improvements Program.

• Expansion: These investments provide more diverse transportation options for communities throughout the Commonwealth. They expand highway, transit, and rail networks and/or services, or they expand bicycle and pedestrian networks to provide more transportation options and address health and sustainability objectives. The MassDOT Highway Division programs in this area include the Bicycle and Pedestrian Program and the Capacity Program. The MBTA’s major expansion program is for the Red-Blue Connector extension of the Blue Line from Bowdoin Station to Charles/MGH Station.

DEVELOPING THE TIP

Project Selection Process

Overview

The MPO applies its investment framework when developing the TIP. The MPO board’s process for selecting projects to receive Regional Target funding relies on evaluation criteria to help identify and prioritize projects that advance the MPO’s goals. The criteria are based on the MPO’s goals and objectives outlined in the LRTP. All projects are required to show consistency with the LRTP and other statewide and regional plans. Other considerations include the readiness of a project for construction and municipal support for the project. Background information about the TIP project evaluation process is presented in Appendix A.

In the wake of the adoption of Destination 2040 in August 2019, the MPO began the process of revising the TIP evaluation criteria to enhance alignment with the MPO’s updated goals, objectives, and investment programs. These new criteria were adopted by the MPO on October 1, 2020, and were employed during the project selection process for the FFYs 2022–26 , 2023–27, and 2024-28 TIPs. The final criteria were the result of a 15-month process that engaged nearly 1,100 members of the public through surveys and focus groups. This process also prioritized the inclusion of significant direct input from MPO members, which was gathered from more than a dozen presentations, discussions, and focus groups. The outcomes of this process are discussed further in the Project Evaluation section on the following pages.

Because of the limitations on in-person gatherings caused by the COVID-19 pandemic, a vast majority of the surveys, focus groups, and presentations discussed above were conducted virtually, with participation options both online and over the telephone. These virtual engagement opportunities allowed MPO staff to pursue new ways of building relationships with members of the public and other key stakeholders in the region. Given the increase in access to the TIP criteria revision process afforded by these virtual events, MPO staff intend to develop a hybrid outreach model that would support both in-person and virtual engagement.

In addition to the process outlined above, which focused on developing new criteria for five of the MPO’s investment programs (Bicycle Network and Pedestrian Connections, Complete Streets, Intersection Improvements, Major Infrastructure, and Transit Modernization), the MPO also adjusted the project selection criteria used to evaluate and fund projects through the Community Connections Program in the FFYs 2022–26 and 2023–27 TIPs. These revisions were made based on the lessons learned by MPO staff through the pilot round of this program, which took place during the FFYs 2021–25 TIP cycle.  MPO staff made no further revisions in the development of the FFYs 2024-28 TIP. More information on these criteria is available in the Project Evaluation section of this chapter, as well as in Appendix A.

Outreach and Data Collection (October–November)

The TIP development process begins early in the federal fiscal year when cities and towns in the region designate staff as TIP contacts and begin developing a list of priority projects to be considered for federal funding. Each fall, the MPO staff asks these TIP contacts to identify their city or town’s priority projects and then MPO staff elicits input from interested parties and members of the general public.

These discussions on municipalities’ priority projects mark the start of a robust dialogue between MPO staff and project proponents that continues through the duration of the TIP cycle. As noted above, these conversations have been taking place virtually because of the COVID-19 pandemic. In November of 2022, MPO staff held two virtual workshops for municipalities in the region to develop an understanding of the TIP process. MPO staff provided additional one-on-one virtual office hours throughout the fall for proponents to ask more detailed questions about advancing specific projects for funding, with several office hour sessions booked for this purpose during the early stages of developing the FFYs 2024–28 TIP.

Once project proponents have decided to pursue federal funding, they must begin the formal project initiation process. All new Bicycle Network and Pedestrian Connections, Complete Streets, Intersection Improvements, and Major Infrastructure projects must be initiated with the MassDOT Highway Division before they can be considered for programming in the TIP. MassDOT details this process on its project initiation webpage, mass.gov/info-details/massdot-highway-initiating-a-project. To be considered for programming, proponents of Community Connections projects must submit an application for funding directly to MPO staff, as these projects do not need to be initiated by MassDOT.

The MPO staff compiles project funding requests for projects into a Universe of Projects list, which consists of all identified projects being advanced for possible funding in the Bicycle Network and Pedestrian Connections, Complete Streets, Intersection Improvements, and Major Infrastructure investment programs. The Universe includes projects that are at advanced stages of project design, those that are undergoing preliminary engineering and design, and projects still in the conceptual planning stage. Those projects that are active municipal priorities and that are feasibly ready to be programmed in the current TIP cycle continue forward into the MPO’s project evaluation process. Projects that are not ready for programming remain in the Universe for consideration in future TIP cycles. A project Universe is not developed for Community Connections projects, as all eligible projects within this program will be considered for funding during the TIP cycle in which project proponents apply.

Project Evaluation (December-February)

The MPO staff uses its project evaluation criteria to logically and transparently evaluate and select projects for programming in the TIP that advance the MPO’s vision for transportation in the region. This process favors projects that support the following goals:

• Transportation by all modes will be safe
• Maintain and modernize the transportation system and plan for its resiliency
• Use existing facility capacity more efficiently and increase transportation options
• Ensure that all people receive comparable benefits from, and are not disproportionately burdened by, MPO investments, regardless of race, color, national origin, age, income, ability, or sex
• Create an environmentally friendly transportation system
• Ensure our transportation network provides a strong foundation for economic vitality

As noted previously, the MPO undertook a process of revising the TIP evaluation criteria prior to the launch of the FFYs 2022–26 TIP to enhance the alignment between the TIP project selection process and the MPO’s updated goals, objectives, and investment programs outlined in Destination 2040. In terms of the overall structure of the criteria, this process resulted in the following outcomes:

• The creation of criteria for the MPO’s Transit Modernization Program, as well as for scoring transit expansion projects through the MPO’s Major Infrastructure Program
• Revisions to the existing criteria for the MPO’s Bicycle Network and Pedestrian Connections, Complete Streets, Intersection Improvements, and Major Infrastructure (Roadway) investment programs, allowing for each program to have a distinct set of criteria that better evaluates the specific aspects of each type of project
• The transition to an overall scoring scale of 100 points (from 134 points under the former scoring system)
• The reconfiguration of the way in which Transportation Equity is scored, from simply being a measure of equity populations in a project area to additionally considering how the most vulnerable people who use the transportation system would benefit from the investments made by a project

In addition to these broader structural changes, a number of updates were made to individual criteria to better accomplish the MPO’s goals in the LRTP:

• The percentage of the overall score allocated to Transportation Equity was more than doubled, from nine percent to 20 percent.
• The multimodal nature of the criteria was enhanced through more fully measuring investments in transit-supporting infrastructure, such as dedicated bus lanes and transit-signal-priority equipment.
• The ways in which the MPO considers resiliency in project selection was broadened by expanding the types of resiliency investments awarded points.
• A new criterion was added that considers the intersection of equity and health through the measurement of the expected emissions impacts of a project in areas with high concentrations of certain air pollutants.

Several other changes were made to the project evaluation criteria, which are detailed in Appendix A. The point distributions by MPO investment program and LRTP goal area are also available in Figure 2-4. Projects scored using both sets of criteria are programmed in each of these four investment programs in the FFYs 2024–28 TIP, so both sets of criteria are referenced throughout this document.

Though many of the adjustments listed above were in development prior to the onset of the COVID-19 pandemic, the emerging lessons from this event reinforced the importance of emphasizing criteria that award points to projects that invest in walking, bicycling, and transit infrastructure. Also, the need for new criteria that more directly address existing disparities in health and transportation access for minorities and low-income households has been put into stark relief throughout the pandemic. While the MPO did not elect to rescore any currently programmed projects with these new criteria, the revised criteria will be employed in coming TIP cycles to support the funding of transportation projects that address the issues highlighted by the COVID-19 pandemic.

Prior to the FFYs 2022–26 TIP cycle, the MPO also undertook a parallel process to update its evaluation criteria for the smaller-scale, first- and last-mile projects considered for funding through the Community Connections Program. These adjustments were based on the lessons learned from the pilot round of this program during the FFYs 2021–25 TIP cycle. In these revisions, MPO staff created a more focused set of criteria that better aligned with the types of projects pursuing funding through this program. Revisions to the Community Connections criteria addressed the discrepancies between capital and operating projects, as the pilot criteria more heavily favored operating projects. These adjustments resulted in more balanced scores that better reflected the goals of the program when implemented for the FFYs 2022–26 TIP cycle. More information on the scoring areas for these criteria is available in Figure 2-3, and all criteria are available in Appendix A. Projects scored using both sets of criteria are programmed in the Community Connections Program in the FFYs 2024–28 TIP, so both sets of criteria are referenced throughout this document.

In order for the MPO staff to conduct a complete project evaluation, each project proponent must provide enough information so that staff can meaningfully apply the evaluation criteria. Bicycle Network and Pedestrian Connections, Complete Streets, Intersection Improvements, and Major Infrastructure projects must have submitted 25 percent design plans to MassDOT, or its plans must include the level of detail defined in a functional design report. (See MassDOT’s Project Development and Design Guide for information about the contents of a functional design report. This guide is available at mass.gov/lists/design-guides-and-manuals.) For Community Connections projects, proponents must submit a complete application to the MPO, including required supporting documentation such as budget sheets, letters of support from partner entities, and work estimates.  

After MPO staff have completed an initial round of project scoring, draft scores are distributed to project proponents for their review. The MPO’s goal is to fairly and accurately assess all projects, making this review a critical component of the TIP process. Proponents are encouraged to submit feedback to MPO staff on their scores if they feel any criteria have been applied inaccurately. Proponents are also encouraged to submit additional supporting documentation on their projects if doing so would help clarify or correct any elements of the draft scoring. MPO staff take all proponent feedback into consideration and make any warranted adjustments to project scores before considering the evaluation process final and preparing the scores for presentation to the MPO.

For more details about the criteria used to score projects and project evaluation results for projects considered for programming in this TIP, see Appendix A.

TIP Readiness Day (February)

On TIP Readiness Day, MPO staff meets with members of the MassDOT Highway Division and Office of Transportation Planning to review cost and schedule changes related to currently programmed projects, which are undergoing design review, permitting, and right-of-way acquisition. The MPO board then considers these updated project construction costs and changes to the expected dates for construction advertisement when making decisions about changes to TIP programming. These changes have an impact on the ability of the MPO to program its target funds for new projects in the five-year TIP.

Between the development of the FFYs 2021–25 TIP and the FFYs 2022–26 TIP, more than half of the projects programmed by the MPO experienced cost increases, many of which represented significant increases in percentage terms or in absolute cost. These changes placed severe limitations on the MPO’s ability to consider new projects for funding during the FFYs 2022–26 TIP cycle. As a partner to MassDOT’s Highway Division and Office of Transportation Planning, the MPO recognizes its role in supporting the on-time and on-budget delivery of projects by proponents. For this reason, the MPO board created a committee in the wake of the FFYs 2022–26 TIP cycle to further explore the causes of project cost increases and devise MPO policy changes to support more reliable project delivery by all parties.

The TIP Project Cost Ad Hoc Committee began its work in June 2021 and advanced a set of policy recommendations to the full MPO board in September 2021. These changes were formally adopted by the MPO on November 4, 2021, and went into effect for the development of the FFYs 2023–27 TIP. In addition to the requirement that project proponents submit 25 percent design plans and obtain an updated cost estimate for their project prior to obtaining funding in the TIP, the committee’s work resulted in several other policy changes. Most notably, the MPO board adopted a policy that proponents of any projects that experienced a cost increase of 25 percent or greater (for projects less than $10 million in cost) or of greater than $2.5 million (for projects more than $10 million in cost) would be required to present to the MPO board on the reasons for these cost increases. The MPO would then compare this project—at its new cost—to other projects based on a cost-effectiveness evaluation before making a decision on whether or not to fund the project at its higher cost. These cost changes are most often revealed through conversations between MassDOT staff and MPO staff during TIP Readiness Day, making this policy especially relevant at this stage of TIP development.

More information on the work of the TIP Project Cost Ad Hoc Committee is available in Chapter 3.

Staff Recommendation and Project Selection (March-April)

Using the evaluation scores and information gathered about project readiness (when a project likely would be fully designed and ready for advertisement) and cost, staff prepares possible TIP project programming scenarios for the MPO’s consideration. When developing these scenarios, MPO staff also considers whether a project was programmed in the LRTP, LRTP-based guidelines for allocating funds to different programs or project types, the distribution of investments across the region, and availability of sufficient funding. The MPO staff gather feedback from board members, project proponents, and the public to inform a final staff recommendation, which is then presented to the MPO for approval before it is included in the draft TIP for public review.

Given the significant increase in Regional Target funding in the FFYs 2024-28 TIP resulting from the passage of the BIL, the MPO selected 21 projects for funding during this TIP cycle, including the following:

• 10 Community Connections projects

• 4 Complete Streets projects
• 3 Transit Modernization projects

• 2 Bicycle Network and Pedestrian Connections projects
• 2 Intersection Improvement projects

In total, the MPO allocated more than $150 million in this TIP cycle to projects not previously funded in the Regional Target program. More information on the projects funded in the FFYs 2024–28 TIP is available in Chapter 3.

Selection Process for Projects Prioritized by the State and Transit Agencies

As discussed above, the selection of transit, bridge, and statewide infrastructure projects for programming in the TIP draws primarily from the CIPs produced by MassDOT and the MBTA. These agencies evaluate projects for inclusion in CIP programs using criteria established by the independent Project Selection Advisory Council (PSAC). The following criteria from the PSAC process guide project evaluation:

• System Preservation: Projects should contribute to a state of good repair on the system and align with asset management goals.
• Mobility: Projects should provide efficient and effective modal options for all users.
• Cost Effectiveness: Projects should result in benefits commensurate with costs and should be aimed at maximizing the return on the public’s investment.
• Economic Impact: Projects should support strategic economic growth in the Commonwealth.
• Safety: Projects should contribute to the safety and security of people and goods in transit.
• Social Equity: Projects should equitably distribute the social, economic, and health benefits of investments among all communities.
• Environmental and Health Effects: Projects should advance state goals of improving air quality and reducing greenhouse gas emissions and pollution.
• Policy Support: Projects should get credit if they support local or regional policies or plans, or state policies not addressed through the other criteria.

Projects that receive the highest priority are those that meet each agency’s goals for maintaining and improving the overall condition and reliability of the system; modernizing the system to make it safer and more accessible and to accommodate growth; and expanding and diversifying transportation options for communities. These project-prioritization processes may also reflect other planning initiatives, such as Focus40, the MBTA’s 25-year investment plan, or MassDOT’s modal plans. More information on regulatory and planning guidance governing TIP project prioritization is available in Appendix E. Once project prioritization is complete, programming decisions are made based on these evaluations and information regarding project readiness, program sizing, and existing asset management plans.

As discussed previously, the transit element of the TIP also includes the Federal-Aid Programs of the other two RTAs in the region, CATA and MWRTA. Once selection processes are complete for all four agencies, these agencies submit their lists of bridge and roadway projects, bicycle and pedestrian improvements, statewide infrastructure items, and transit capital projects to the MPO for review.

APPROVING THE TIP

Approval of the Draft TIP for Public Review

The MPO board considers the project evaluation results and staff recommendation when prioritizing projects for Regional Target funding. The board also considers public comments, the regional importance of projects, and other factors. In addition to prioritizing the Regional Target funding, the MPO board reviews MassDOT’s proposed statewide highway programming and the proposed capital programs for the MBTA, CATA, and MWRTA before voting to release a draft TIP for public review.

The MPO board votes to release the draft document for public review and invites members of the public, municipal and elected officials, and other stakeholders in the Boston region to review the proposed TIP. The MPO staff hosts outreach events during the public review period to elicit comments on the draft document. (See Appendix C for a full list of public comments submitted on the draft TIP.)

Approval of the Draft TIP

After the public review period ends, the MPO staff and board review all public comments, and the board may change the programming or the document as appropriate before endorsing the TIP. MassDOT staff incorporates the MPO-endorsed TIP into the State Transportation Improvement Program (STIP) and submits it to the FHWA and FTA for approval. The FHWA, FTA, and US Environmental Protection Agency review the STIP and certify it by September 30, the end of the federal fiscal year.

UPDATING THE TIP

The TIP is a dynamic program that may be amended and adjusted throughout the year. Administrative modifications and amendments are often introduced because of changes in project status (advertisement readiness), project cost, project design scope, or available revenue. An amendment is a revision that requires public review and a demonstration of fiscal constraint.

Consistent with federal guidelines, the Boston Region MPO must release an amendment if there is (1) a change in project cost of $500,000 or more for projects valued at $5 million or less, or (2) a change of 10 percent or more of the project cost for projects valued greater than $5 million. TIP amendments are also released if there is a proposal to add or remove a project from the TIP or if the programming year of a project is changed. Cost changes that are less than the above threshold amounts may be considered in the form of administrative modifications or adjustments, which must still undergo MPO board action for approval. Administrative modifications or adjustments are also undertaken in the event that a project’s funding source changes. Although a public review period is not required for administrative modifications or adjustments, one may be offered at the MPO board’s discretion.

Regardless of the nature of an amendment, all proposed TIP amendments are presented in a public setting at an MPO meeting, and details are posted on the MPO’s website, bostonmpo.org. Public notices are distributed through the MPO’s email contact list, which members of the public may join by signing up on the MPO’s website. Municipal staff who are TIP contacts at the affected municipalities and the public are notified of pending amendments at the start of an amendment’s public review period.

A history of TIP Amendments can be found at https://www.ctps.org/tip.

Public Notice

Notices of draft TIP amendments include a summary of the amendment’s contents, dates of the public review period, contact information for submitting a comment to the MPO, and the date, time, and location that the MPO will vote on that amendment. Municipal representatives and members of the public are invited to submit written or oral testimony at the MPO meetings at which amendments are discussed or voted upon.

The MPO typically holds a 21-day public review period before taking final action on an amendment. In extraordinary circumstances, the MPO may vote to shorten the public review period to a minimum of 15 days. These circumstances are detailed in the MPO’s Public Engagement Plan.

The MPO’s website is the best place to find current information about the TIP. All changes to the draft TIP and changes to the endorsed TIP, such as amendments and modifications that have been approved by the MPO, are available on the TIP webpage, bostonmpo.org/tip.

Comments or questions about the draft TIP materials may be submitted directly to the MPO staff via the website, email, or US mail, or voiced at MPO meetings and other public MPO events.

Chapter 3: Summary of Highway and Transit Programming

Chapter 3—Highway and Transit Programming

The Transportation Improvement Program (TIP) tables included in this chapter present a listing of all the projects and programs funded with federal highway and transit aid in the Boston region during federal fiscal years (FFYs) 2024–28. These funding tables are also included as part of the State Transportation Improvement Program (STIP).

Table 3-1 presents a summary of the Boston Region Metropolitan Planning Organization’s (MPO) share of Regional Target funds from the Federal-Aid Highway Program. The allocation of these funds is constrained by projections of available federal aid. As shown in Table 3-1, the MPO has programmed much of the available discretionary funds within the limits of projected funding for highway funding programs. As such, the FFYs 2024–28 TIP Regional Target Program complies with financial constraint requirements.

Table 3-1
Boston Region MPO Regional Target Program
Funding Summary

As discussed in Chapter 2, the signing of the Bipartisan Infrastructure Law (BIL), on November 15, 2021, increased the amount of Regional Target funding available to the Boston Region MPO for the development of the FFYs 2024–28 TIP by approximately nine percent from the funding levels in the FFYs 2023–27 TIP. The projects selected by the MPO for funding for the first time in the FFYs 2024–28 TIP are listed in Table 3-2.

During the development of the FFYs 2024–28 TIP, the MPO had significant amounts of funding available to program for each fiscal year. This surplus was driven by programming delays for nine projects.

Projects already programmed in the TIP to receive Regional Target funds could not be accelerated, so the MPO worked with the Massachusetts Department of Transportation (MassDOT) and the Massachusetts Bay Transportation Authority (MBTA) to identify other projects that could be funded in these fiscal years. Jointly, MassDOT and the MBTA presented more than a dozen projects to the MPO for consideration, from which the MPO selected five projects for funding in FFYs 2024 and 2025:

• Columbus Avenue Bus Lanes Phase 2

• Rail Transformation Early Action Items—Reading Station and Wilbur Interlocking

• Jackson Square Station Accessibility Improvements

• Chelsea—Targeted Safety Improvements and Related Work on Broadway, from Williams Street to City Hall Avenue

The MPO also selected one MassDOT project for funding in FFY 2027:

• Everett—Targeted Multi-Modal and Safety Improvements on Route 16

The MPO staff has not yet evaluated these projects using the MPO’s project selection criteria because of time constraints associated with the MPO board’s deadlines for making decisions about project funding. However, these projects generally align well with many of the MPO’s goals, including enhancing bicycle and pedestrian safety and access, and expanding the accessibility of and maintaining a state of good repair for the region’s transit system and critical roadways. Scoring information for these projects will be included in the TIP when it is available.

In addition to the project selection, several other key decisions were made by the MPO in the drafting of the FFYs 2024–28 Regional Target Program:

• The MPO introduced a Bikeshare Support Set-Aside line item to fund capital repair and improvement projects for bikeshare initiatives in the region starting in FFY 2025. This line item is funded at $1 million per year for FFYs 2025 and 2026 and $2 million per year for FFYs 2027 and 2028.

• The MPO has allocated $4 million of Regional Target funding for a pilot initiative in FFY 2025 to support municipalities that are designing projects. The aim is to provide support earlier in a project’s lifecycle and increase the number of projects in the funding pipeline.

• The programmed amount of Project 607981, Somerville—McGrath Boulevard Construction, was increased by $15 million in FFY 2027. The overall budget for the project remains the same and has been rebalanced for accelerated construction.

• The $6.4 million contribution by the MPO to the MBTA’s Forest Hills Station Improvement Project in FFY 2024 was removed due to the lack of funding availability from other contributors.

Additional details of the specific projects programmed with Regional Target funding are shown in Section 1A of each annual element of the TIP tables (Table 3-7). The other sections in Table 3-7 (Sections 1B, 2A, 2B, 2C, and 3B) list the following:

• Projects funded with earmarks or discretionary grant funds
• State-prioritized bridge repairs and rehabilitation, pavement maintenance, safety improvements, retrofits for accessibility (as required by the Americans with Disabilities Act), intersection improvements, roadway reconstruction, and bicycle and pedestrian projects

Tables 3-8, 3-9, 3-10, and 3-11 list the federally funded transit projects and programs in the Boston region that the MBTA, MetroWest Regional Transit Authority (MWRTA), and Cape Ann Transportation Authority (CATA) plan to undertake.

Detailed descriptions of projects funded through both the Regional Target and statewide portions of the Highway Program follow the tables. The descriptions note the evaluation scores (for MPO-funded projects), project proponents, and funding details. The pages are organized alphabetically by the municipality in which each project is located.

Investment Summary

This section summarizes the investments made by the Boston Region MPO, MassDOT, MBTA, CATA, and MWRTA that are documented in the FFYs 2024–28 TIP. Table 3-3 shows the Boston Region MPO’s investments of Regional Target funding—including both the number of projects and the dollar amount—by investment program. These investments are aimed at making progress towards the MPO’s goals for the region, including enhancing safety for all users, preserving and modernizing the transportation system, promoting mobility and reducing congestion, supporting clean air and sustainability, ensuring all have equitable access to the transportation system, and fostering economic vitality in the region through investments in transportation.

The MPO’s Regional Target Program increased in size by approximately $52 million between the FFYs 2023–27 TIP and the FFYs 2024–28 TIP to a total program size of more than $697 million.

Table 3-4 shows MassDOT’s FFYs 2024–28 TIP investments—including both the number of projects or programs and the dollar amount—organized by MassDOT program. MassDOT’s investments are distributed across a variety of programs and will support bridge and pavement improvements, roadway improvements and reconstruction, new bicycle and pedestrian infrastructure, and safety improvements. More details on these investments are available on the project description pages in the second section of this chapter.

As detailed above for the MPO’s Regional Target Program, the BIL significantly increased the funding available to MassDOT for programming projects in the statewide Highway Program. Most notably, the BIL’s Bridge Formula Program allowed MassDOT to increase the funding allocated to federal-aid bridge projects. Furthermore, FFY 2026 represents the conclusion of grant anticipation notes (GANS) payments for MassDOT’s Accelerated Bridge Program (ABP).  As this program winds down, the passage of the 2021 Massachusetts Transportation Bond Bill and the new federal funding available through the BIL has allowed for the creation of MassDOT’s Next Generation Bridge Program (NGBP).

Like the ABP, the NGBP leverages state bonding capacity to accelerate the rehabilitation and replacement of critical or structurally deficient bridges across Massachusetts. In the FFYs 2024–28 TIP, 15 bridge projects are funded by MassDOT through the NGBP using state bond bill funds. These projects are shown in the TIP as debt payments on these bonds, which will use future federal formula funding.

Continued funding from the BIL supports increased investment across MassDOT’s other programs in the FFYs 2024–28 TIP, including the Bicycle and Pedestrian Program, the Intersection Improvements Program, the Interstate and Non-Interstate Pavement Programs, the Roadway Reconstruction Program, and the Safety Improvements Program. MassDOT’s Highway Program has increased by more than $1.1 billion between the FFYs 2023–27 TIP and the FFYs 2024–28 TIP to a total program size of more than $3.1 billion over five years.

Table 3-4
FFYs 2024–28 MassDOT Highway Program Investment Summary

Note: Funding amounts in this table include both federal and non-federal funds, including matching funds.

* Three projects receiving earmark funding are also receiving funding through other sources: Project 607977—Interstates 90/495 Interchange Reconstruction—is funded through MassDOT’s Roadway Reconstruction and NFA Programs; Project 605313—Natick Bridge Replacement over Route 9 and Interchange Improvements—is funded through MassDOT’s Bridge On-System NHS NB Program; and Project 608436—Ashland Rehabilitation and Rail Crossing Improvements on Cherry Street—is funded through MassDOT’s Railroad Crossings Program. Each project is counted in the tally for each funding category but is only counted once in the total number of projects funded.

Table 3-5 shows the MBTA’s programs and associated FFYs 2024–28 TIP funding amounts. Additional details on the MBTA’s programs and projects are in Tables 3-8 and 3-9. The MBTA’s capital program is substantially similar between FFYs 2023–27 TIP and the FFYs 2024–28 TIP, increasing from a total program size of $3.93 billion to $3.99 billion. Investments made through these programs allow the MBTA to continue to maintain and modernize its infrastructure in support of the agency’s role as the largest transit provider in the Commonwealth of Massachusetts.

The MBTA caters to a wide range of needs, serving the Boston region with commuter rail, light rail, subway, fixed-route bus, and paratransit services. The MBTA prioritizes projects that keep the existing transit system in a state of good repair, including the purchase of new rolling stock, accessibility and resiliency improvements to stations, the rehabilitation of bridges and tunnels, and the replacement of tracks and signals to support system-wide reliability. Limited system expansion projects are also undertaken through the MBTA’s federal capital program. Further information on how the MBTA’s investments support system safety and condition is available in Chapter 4.

Note: Federal Transit Administration formula funds (Sections 5307, 5337 and 5339) are based on estimated apportionments for FFYs 2024–28. These apportionments include additional funding to be made available through the Bipartisan Infrastructure Law, based on current estimates. TIP programs and projects are based on a preliminary draft Capital Investment Plan (CIP) as of April 2022. Adjustments will be made to federal projects and budgets as the CIP process is finalized. Funding amounts in this table include both federal and non-federal funds, including matching funds.

* Positive Train Control investments are funded with RRIF funds.

Table 3-6 summarizes CATA and MWRTA investments included in the FFYs 2024–28 TIP, and more information is available on each agency’s investments in Tables 3-10 and 3-11. Though the MBTA provides commuter rail service to the Cape Ann communities of Rockport and Gloucester, CATA provides additional paratransit and fixed-route bus services to these communities and to Danvers, Peabody, Ipswich, Essex, and Beverly. CATA’s federal capital program supports its role in providing critical transportation alternatives to residents and visitors of the area, including through the replacement of buses, the modernization of facilities, and the maintenance of assets.

MWRTA similarly complements MBTA commuter rail service, operating fixed-route bus, on-demand microtransit, and commuter shuttle services to a number of communities in the MetroWest subregion. MWRTA’s federal capital program supports this mission by funding vehicle replacements, station and facility maintenance and improvements, and operating assistance for paratransit services, among other efforts. Other projects funded in MWRTA’s 2024–28 TIP include the electrification of the agency’s paratransit fleet and investments in technology to support travel training and customer service efforts.

Overall, the program size for CATA is substantially similar in the FFYs 2024–28 TIP to its figures in the FFYs 2023–27 TIP, while the program size for MWRTA increased by a greater amount. These agencies collectively received an approximately $9.7 million increase in funding levels in this TIP for a total program size of more than $65.3 million.
