MBTA advances Green Line D track, signal replacement project

The Massachusetts Bay Transit Authority (MBTA) last week began construction on the Green Line D Track and Signal Replacement project.

The project calls for replacing 25,000 feet of track and 6.5 miles of signals on the Green Line, specifically between Beaconsfield and Riverside on the D Branch. 

The new tracks and signals are expected to mitigate risk of service interruptions due to track conditions, and reduce time and money needed for maintenance, MBTA officials said in a project update.

Budgeted at $101.6 million, the project is 72% complete and expected to wrap up in fall 2021.

Part of the MBTA's Green Line Transportation, the project will result in speed restrictions being lifted on some sections of the Green Line for faster service.
