The Silver Line - Project Description

The Silver Line will provide improved service from Dudley Station in the Roxbury section of Boston to a final destination of Logan Airport. The service will run via downtown Boston, the South Boston Piers area and the airport, making these major job centers accessible with a one-seat ride. The groundbreaking ceremony for the Washington Street portion of the project took place on September 28, 2000.

Phase I consists of service from Dudley Station to downtown Boston in a dedicated lane. The vehicles will be 60' articulated, alternative-fuel (CNG) buses with state-of-the-art intelligent transportation systems (ITS) technology. Construction of this phase began in 2000 and opened on July 20, 2002. The project includes complete reconstruction of Washington Street with new sidewalks, lighting, landscaping and transit stations.

Phase II consisting of a tunnel from South Station to the South Boston Piers area, opened in 2003, should be completed in 2003 and operational in January 2004. The project includes a one-mile tunnel, three stations, dual-mode vehicles and a maintenance facility. The Line will provide service to Logan Airport via the Ted Williams Tunnel and to a new Convention Center (under construction). New 60 foot low-floor articulated dual-mode buses would provide service in Phase II.

Phase III of the project will extend the tunnel to the MBTA's Green Line in the downtown area and allow for the connection of Phase II and Phase III. This connection will provide a one-seat ride from Roxbury to Logan Airport and connections to the central subway lines. This project has the potential of being the most heavily used line segment of the system and the first of a Bus Rapid Transit System that has excellent expansion possibilities. Preliminary engineering (PE) for Phase III was authorized in July 2002. However, the notice to proceed began in early 2003.
