SOMERVILLE, MA — An updated schedule for Green Line Extension bridge closures in Somerville was released by the project team Monday. The revised timeline indicates the opening of all three bridges currently closed for GLX work will be delayed.

The Broadway bridge in Ball Square is now expected to open in July, about four months later than anticipated; the Washington Street bridge will reopen in May; and the Medford Street bridge will reopen in October. The School Street and Medford Street bridges have not yet closed, and the new schedule shows they will close concurrently for about four months this summer and fall.

In his testimony before the MBTA's Fiscal Management Control Board today, Somerville Mayor Joseph Curtatone said the city is "deeply disappointed" by the delays and will need additional assistance to address the impact of the closures. He said his community has had to shoulder a difficult burden during construction and will work with the MBTA and MassDOT to reduce its effects, including advocating for assistance with public safety and traffic management and support for local businesses .
