BOSTON: Commonwealth Avenue Bridge Replacement

April 11, 2017

Massachusetts Department of Transportation (MassDOT)  will be replacing the Commonwealth Avenue Bridge this coming summer. The project will replace the existing bridge that carries Commonwealth Avenue and the MBTA Green "B" Line over I-90, the Massachusetts Turnpike, and the MBTA Commuter Rail line. The Commonwealth Avenue eastbound and Green Line segments will be replaced in 2017, with the westbound side following the summer of 2018.

Here is an animation of the project:
