Green Line Extension Overnight Work Tonight At School St. Bridge in Somerville

The Green Line Extension Project (GLX) team wanted to inform you of overnight work scheduled to start tonight at midnight and last through 7AM Thursday morning (June 4).  The GLX contractor, White Skanska Kiewit (WSK), will be performing work at School Street Bridge in Somerville in conjunction with the School Street Bridge work & lane closure which began in April 2015. This work, an important step in bringing the Green Line from Cambridge to Medford and Somerville, will take place inside the current work zone and will not further impede traffic.

WSK is currently preparing the foundations of the utility bridge being erected alongside School Street Bridge. In order to complete this, WSK will transport a drill rig across the railroad tracks to clean out the foundation shafts, then move the drill rig back across the tracks in the early hours of Thursday morning. The work is being coordinated around the train schedule because the tracks need to be clear before the first commuter train comes through in the morning.

Should you have any questions please feel free to contact the Green Line Extension at 855-GLX-INFO (459-4636) or
