Reminder: Medford Street Bridge on Schedule to Close on Friday, May 17

Posted on May 14, 2019

The MBTA is reminding the public that the Green Line Extension (GLX) project will close the Medford Street Bridge near Gilman Square in Somerville on the evening of Friday, May 17, 2019. The bridge will remain closed through the spring of 2020.

The closure of the Medford Street Bridge will allow an accelerated pace of work for 2 major construction projects underway adjacent to the bridge:

  • The City of Somerville High School project will utilize areas of the Medford Street roadway for short-term construction staging operations through June 2019.
  • The GLX project will simultaneously begin needed modifications to the bridge, creating a longer span with structural improvements to accommodate the new Green Line tracks that will be installed beneath the roadway.

Traffic Detour

For the duration of this closure, all traffic will be detoured around the work zone via Pearl Street and McGrath Highway.

Detour maps and directions are available at www.mass.gov/GLX, in the Bridge Closures section

Map of Medford Street Bridge Closure Traffic Detour. For traffic headed north/west: Bear right on McGrath Highway at Medford Street, left on Pearl Street, and right on Medford Street. For traffic headed south/east: From Medford Street, bear left on Pearl Street, right on McGrath Highway, and continue on McGrath Highway.

Recent schedules had projected the Medford Street Bridge would close in July 2019, but this new timeline was established after careful coordination between the Green Line Extension project and the Somerville High School Building project, which are progressing in close physical proximity to one another. Advancing the Medford Street Bridge closure by 6 weeks will provide critical logistical benefits for both projects.
