Bus connections Tufts Medical Center serves both routes of the Washington Street section of the Silver Line, which operates between downtown and . The SL4 section serves South Station, while the SL5 section serves Downtown Crossing and Boylston. Silver Line buses stop at the primary station entrance on Washington Street. The station also sees conventional bus service from three MBTA bus routes. Routes and run on Washington Street and stop at the same location as the Silver Line, while route runs on Tremont Street and is accessed through the station's secondary headhouse. History In 1914, the Boston Transit Commission considered constructing a station at Bennet Street where the Washington Street Tunnel rose to the surface to meet the Washington Street Elevated. The proposal was rejected due to the steep grade and the proximity to Boylston station. In September 1968, the MBTA began construction of the shell of a station - then called South Cove - and the South Cove Tunnel during what were to be the early stages of the abandoned Interstate 695 project, in anticipation of the future relocation of the Washington Street Elevated. The relocated Orange Line was to run in the median of the extended I-95 in the Southwest Corridor, then replace service on the Needham Line to Needham. Due to a lack of available federal funds, the MBTA financed the $13.3 million project with local bond funds. The tunnel (which reached to Marginal Street) and the station shell were completed in 1972. However, I-695 was cancelled due to local opposition in 1971; the Elevated remained in service, and the South Cove Tunnel and station sat unused. After the plans for I-95 to be extended into downtown fell through in 1973, the state began looking to use the Southwest Corridor for a combined Orange Line and commuter rail corridor. In 1975, the MBTA applied for $29 million in federal grants to extend the South Cove Tunnel
