Backlogged Green Line Extension Work To Start At Night

MEDFORD, MA — MassDOT announced additional nighttime work on the Green Line Extension as the project continues at a "rapid pace" to make up for supply chain issues during the pandemic.

Construction is about "80 percent complete" ahead of the extension's projected opening this fall, MassDOT said.

Work hours may be sporadic at times, but notable night work includes:

• In the Brickbottom Condominium area off Fitchburg Street in Somerville, wall panel placement will proceed around-the-clock on Friday and Saturday (June 18 and 19). This work will primarily focus on the viaduct walls along the GLX Union Branch and Fitchburg Commuter Rail Line. Residents should expect the use of heavy machinery and engine noise.

• On the entire east/north side of the Medford Branch (from Monsignor O’Brien Highway to Medford/Tufts Station), wall panel placement work will continue at night on a sporadic basis over the next few weeks. Residents should expect the use of heavy machinery and engine noise.

• In addition to wall panel placement, signal and electrical work is expected in and around the station areas at night. This work is typically quieter than wall panel placement, as it does not generally require the use of heavy machinery.

Trucks and heavy equipment modified to operate on rails will be in use along both branches. In addition, the yellow construction train known as the Multi-Purpose Machine (MPM) will be used at night within work zones along the entire Medford Branch. These vehicles are required by federal law to sound their horns during frequent stops and starts.
