South Boston Piers Transitway - Phase I

Boston, Massachusetts

(November 1996)


The Massachusetts Bay Transportation Authority (MBTA) is developing an underground transitway connecting the MBTA's existing transit system with the South Boston Piers area. The Piers area, which is connected to Boston's central business district by three local bridges, is slated for significant future development. Electric powered trackless trolleys or dual-mode vehicles will operate on the transitway and on limited surface routes in the eastern end of the Piers area. Phase I of the project, a one-mile connector between South Station (Red Line, commuter rail, bus, Amtrak) and the World Trade Center is estimated to cost $413.4 million (escalated dollars). Daily ridership in the Piers area is estimated to range from 22,000 trips in the low growth scenario to 34,100 trips in the high growth scenario. Phase II would extend the Transitway to the Chinatown Station on the Orange Line and the Boylston Station on the Green Line.


Section 3035(j) of ISTEA directed FTA to enter into a multiyear grant agreement with the MBTA for $278 million. The MBTA completed alternatives analysis and selected a locally preferred alternative in February 1993. The final EIS was published in December 1993. The project has commenced with final design and some construction activities.

In November 1994, the FTA signed a Full Funding Grant Agreement (FFGA) with the MBTA for $330.73 million, which included a contingent commitment for $53 million. The agreement covers final design and construction of Phase I. The project is expected to open for revenue service in December 2000.
