Boston, Massachusetts/South Boston Piers Transitway - Phase I
South Boston Piers Transitway - Phase I
The Massachusetts Bay Transportation Authority (MBTA) is developing an underground transitway connecting the MBTAís existing transit system with the South Boston Piers area. The Piers area, which is connected to Bostonís central business district by three local bridges, is undergoing significant development. Dual mode trackless trolleys are projected to operate in the transitway and on limited surface routes in the eastern end of the Piers area. Phase I of the project, a one mile tunnel connector between South Station and the World Trade Center, is now currently estimated to cost $601 million (escalated dollars) according to a recently submitted recovery plan. The need for a recovery plan was caused by increased cost growth and delays in the projectís implementation schedule. The revised cost reflects an increase of $187.59 million over the original project cost, which will be paid for with non-Section 5309 New Starts funds. South Station is a transportation key hub in the downtown area, serving the MBTA Red Line and local bus, commuter rail, intercity bus, and Amtrak. Daily ridership for the Transitway in 2010 is estimated to range from 22,000 trips in the lower-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.
The MBTA completed the alternatives analysis process and selected a locally preferred alternative in February 1993. The Final Environmental Impact Statement was published in December 1993. The project is under construction. In November 1994, FTA signed a Full Funding Grant Agreement (FFGA) with the MBTA with a commitment of $330.73 million in Section 5309 New Starts funds. The FFGA covers final design and construction of Phase I. To address cost growth and project schedule delays, FTA required the submission of a project recovery plan by the MBTA. MBTA has prepared and submitted a recovery plan, which is currently under review by FTA. The project is now estimated to open for revenue service in December 2003.
Through FY 2001, Congress has appropriated $319.53 million in Section 5309 New Starts funds for the South Boston Piers Transitway.
