Medford St. Detour Details


Phase 1 Project Description

Beginning on Monday, July 21, 2014 for approximately three weeks, Medford Street in Somerville will be closed to traffic between McGrath Highway and Ward Street to allow for top coat painting of the Medford St. Railroad Bridge.

Pedestrians will still have access through Medford St. as one sidewalk will remain open during the duration of the closure.

The traffic diversion Detour Map is available as a PDF to view and save for printing.

This work is part of the widening of the Medford Street Railroad Bridge to allow for Green Line tracks to run alongside the Commuter Rail tracks.

Thank you in advance for your patience. This work is an important step in bringing the Green Line to Somerville.

As always, if you have any questions, you can email us at or contact the Green Line Extension Project at 855-GLX-INFO (855-459-4636).
