About The Project

On October 31, 2014, MassDOT submitted a Draft Environmental Impact Report (DEIR) for the South Station Expansion project to the Massachusetts Secretary of Energy and Environmental Affairs. The Secretary issued a MEPA Certificate on December 31, 2014.

The project would acquire and demolish the USPS facility, reopen Dorchester Ave. and extend the Harborwalk, expand the South Station terminal, improve reliability and meet current and future commuter rail, high-speed, intercity, and rail service needs, and create new layover capacity.

MassDOT is simultaneously performing environmental review of the I-90 Allston Interchange Project, which includes the Beacon Park Yard rail site and I-90 (the Massachusetts Turnpike) for midday layover storage.

MassDOT is committed to comprehensive and inclusive civic engagement as part of the South Station Expansion project. Please explore the website for additional information, and feel free to contact Steve Woelfel, Deputy Director, MassDOT Office of Transportation Planning.
