Written by Press Release
The MBTA was able to execute accelerated construction on the Green Line.

The MBTA announced [yesterday] it will continue to advance with another series of major crane lifts this weekend at the new Lechmere Viaduct now under construction between the Gilmore Bridge and Lechmere Station along Monsignor O’Brien Highway. The operation, now in its fifth consecutive weekend work window, continues to progress as planned.

The activity is in support of the Green Line Extension (GLX) project. Crane equipment setup and traffic detours will be in place by 5 AM on Saturday, August 8. The placement of large steel beams will support the deck of the new viaduct section. Crane lifts are scheduled from 7 AM to 10 PM on Saturday and from 7 AM to 7 PM on Sunday.

Traffic detours for motor vehicles, pedestrians, and bicyclists traveling through the area along Monsignor O’Brien Highway will be in place throughout the weekend. The GLX project will extend Green Line service from the new Lechmere Station along 2 new branches to Union Square in Somerville and to College Avenue/Tufts University in Medford.

Anticipated noise levels during the overnight periods are expected to be light to moderate.
