The MBTA Government Center Station Project construction timeline has been updated for the planned two-year full station closure.
MassDOT Secretary Richard A. Davey directed the MBTA to keep the station open until after the reopening of the Callahan Tunnel, which is scheduled to be closed for repairs between late December and the end of March 2014. Government Center Station construction will begin this fall but will be done without closing the station until the Callahan Tunnel reopens.
The $91 million, three-year Government Center Station Project will bring the new station into compliance with the Americans with Disabilities Act and includes improvements to the Green Line Station, Blue Line Station, and Cambridge Street/Government Center Plaza.
The project includes reconstruction of both the Green Line and Blue Line platforms, new elevators from the surface to the Green Line level and from the Green Line level to the Blue Line level, a new headhouse structure as the primary entrance to the Station, and reconstruction of Cambridge Street and City Hall plaza in the vicinity of the station.
The project will close Government Center Station for 24 months during the construction period by diverting passengers to other nearby stations. Temporary closure of the station to patrons eliminates the need for a temporary headhouse, avoids numerous weekend and nightly closures, and allows construction to proceed more rapidly, reducing the overall construction schedule.
