The Massachusetts Department of Transportation (MassDOT) is planning to undertake the South Station Expansion project in Bostan, Massachusetts, the US.

The project involves the addition of five to seven additional train platforms and relocation of the postal facility; the extension of the commuter rail to New Bedford and Fall River and Silver Line bus service to Chelsea; the construction of a new commuter rail station in Allston, called West Station; new trains — called “diesel multiple units” — to run from Newton to the South Boston waterfront, site of the proposed Olympic stadium, on existing rail lines; statewide commuter rail enhancements; a new Massachusetts Turnpike interchange at the Allston tolls; all-electronic tolling on the Pike; and accelerated bridge repairs statewide.

The work will includes the construction of new passenger facilities, four platforms, street scape, pedestrian ways, bicycle, local transit, and vehicular facilities in and around the station, including tracks, platforms, waiting areas with connections to existing platforms and tracks and the adjacent South Station Bus Terminal.

HNTB and Vanasse Hangen Brustlin, Inc. (VHB) were appointed for project management, project controls, rail engineering, architecture, general engineering, transportation planning, environmental services, land-use planning, funding, delivery.

ARCADIS and KM Chng Environmental were appointed as the consulting engineer, Bryant Associates Inc. was awarded the contract for survey works, Epsilon Associates Inc as environmental consultant.

Architectural works were awarded to Stull & Lee Inc., VJ Associates was appointed as cost engineer and Utile, Inc. as master planner.

In September 2011, U.S Department of Transportation has granted US$33 million fund to finalize expansion plan of Boston’s South Station and US$245 million fund was received from the state budget.

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

As of June 2016, MassDOT plans to submit a Final Environmental Impact Report (FEIR), which includes a preferred South Station Expansion alternative, summarizes the changes to the project since the DEIR filing in 2014, and incorporates the additional environmental analyses outlined in the Certificate on the DEIR. The FEIR provides responses to comments received on the DEIR.

There are new concerns that an expansion could hurt surrounding neighborhoods. Opponents are concerned about where those extra trains will be stored, and the potential for poor use of valuable land.

MassDOT is finalizing the FEIR filing schedule, public meeting dates and additional materials. Please revisit this website soon for more information.

In addition, MassDOT is preparing an Environmental Assessment (EA) under the federal National Environmental Policy Act (NEPA). The EA will be released in 2017.

Federal Railroad Administration (FRA) grant of $32.5 million will expire in June 2017 and study must be completed by then or MassDOT could be required to reimburse the FRA

In March 2017, Draft Environmental Assessment (EA) and Draft Section 4(f) Determination was released.

With a submission deadline of May 27, 2017, FRA and MassDOT accepted comments on the Draft EA.

As of July 2017, FRA is reviewing comments and will issue a NEPA decision, a Finding of No Significant Impact, if appropriate. Upon issuance of a NEPA decision document, the environmental review will be complete.
