For the next phase of work on the Green Line Extension (GLX) 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. Detour maps and directions are available on www.mass.gov/GLX in the “Bridge Closures” section.

A longer bridge with structural improvements will be constructed to accommodate the light rail tracks. The new bridge will also feature a portion of the extended Community Path, and major utilities beneath the roadway will be replaced and relocated.

The Somerville Bridge Hopper, the City’s free shuttle to help transport residents from one side of the closure to the other, will offer service on Washington St. starting Tuesday, April 9. Shuttles will operate weekdays between 7 a.m. and 7 p.m. More information will available onwww.somervillema.gov/GLX and signage will be posted at each shuttle stop in the coming days.
