In case you didn't know; currently, there are two major detours in Somerville due to the Green Line Extension Project.
Until next year, drivers will have to seek alternative routes when nearing the Washington street underpass. Also, you will have to seek alternative routes when nearing Ball Square, as the Ball Square bridge is undergoing construction for the Green Line.
The project is expected to last until around March of 2020.
Note: MBTA bus routes 86 and 91 will be taking exceptionally longer detours from Sullivan Square station.
