For the next phase of work on the Green Line Extension Project, the Washington St. bridge, in East Somerville near McGrath Highway, will close for construction beginning Monday, April 8, at about 10 p.m. This bridge will close for two separate phases: first, from April 8 through approximately November 2019, then again from about April 2020 through August 2020.

During closures, all traffic will be detoured around the bridge’s underpass, including motorists, cyclists, pedestrians, and MBTA bus routes 86, 91, and CT2. You can find more information about the project and detours at
