Note: The "Green Line CIG-Core Capacity (Proposed Funding)" line item represents a preliminary estimate of the MBTA’s future FTA CIG-Core Capacity grant application and is a demonstration of the MBTA’s participation in the discretionary program. If awarded, this grant would support a number of Green Line Projects intended to increase system capacity by no less than 10%. Each Project will be funded by a combination of FTA Core Capacity grant funds, FTA Boston UZA formula funds and MBTA local match. This line item only reflects the proposed Core Capacity funding. Projects P0591, P1010, P0921, P1102, P1105, P0920, P1011, P1103, P1101, P1136, P0923, P1334, P0922, P1337, P1338, and P0924 are approved in the transit element of the endorsed FFY25-29 Boston Region TIP and the Transit Investment Report of the FFY25-29 Massachusetts STIP. These Projects are elements of the MBTA’s Core Capacity application and are identified in the table above. Through the MBTA CIP, Boston Region TIP, and Massachusetts STIP, MBTA has committed the use of $282,025,316 of Boston UZA 5337 formula funding to support the completion of these projects. Upon award, Projects, budgets, and funding sources will be amended as required.

Note: The MBTA is exploring the use of federal loans through the Build America Bureau to finance certain capital projects at a lower interest rate than traditional tax-exempt bonds. This includes loans under the Railroad Rehabilitation & Improvement Financing (RRIF) and Transportation Infrastructure Finance and Innovation Act (TIFIA) programs. The projects listed above are being considered for this program, subject to the approval of funding through the CIP process. Additional project and funding information will be provided through a future TIP/Amendment if federal grant funds or loans are utilized.
