MBTA Green Line Extension Project Road Closure


As part of the MBTA Green Line Extension Project, the Medford Street Bridge in Somerville will be demolished. During this phase of the project, The Medford Street underpass will be closed to all traffic from July 5 through July 21 (24 hours a day/7 days a week). Many Cambridge residents use Medford Street to exit and enter the City of Cambridge. Please view the detour map below. This important project will extend existing MBTA Green Line service from a relocated Lechmere Station in East Cambridge to Union Square in Somerville and College Avenue in Medford. For more information on the MBTA Green Line Extension Project, please click here.
