Union Square Station

Overview of work in the area: Station and support facility construction is well underway not far from the Prospect St. bridge. Between this area and where the track runs under McGrath Hwy., the GLX project has been building retaining walls along the track to support the new light rail track.

Work Schedule: Monday – Friday, with frequent weekends.

Work Planned for the next few weeks: The work at Union Square Station continues to take shape. Expect to see steel for the station going into place this month. System, rail bed, and track installation will continue throughout this section of the rail alignment.

Night Work: No night work is anticipated at this time.

Lechmere Station

Overview of current work in the area: Work continues on building a new, elevated Lechmere Station on the north side of Monsignor O'Brien Highway. Demolition of the old viaduct was completed on June 21 and work is now focused on the continued construction of a new viaduct from the Gilmore Bridge to the new Lechmere Station. Trolley service to the Lechmere Station stopped on May 24 and was replaced by bus service to and from North Station.

Work Schedule: Monday – Friday, with occasional nights and weekends.

Work Planned for the next few weeks: Viaduct construction will continue to advance through various stages from Lechmere north towards the East Somerville Station. Only one more span remains without steel and that section will be placed during this period. The highest elevated section of the Community Path will continue to take shape and steel is now being placed on the remaining levels of concrete piers.

Work will remain active during this period at ground level and track level on the new Lechmere Station. The placement of vertical steel elements for the station awnings and amenities is expected to begin in October. This includes steel for the north and south headhouses, elevator towers, and stairwells. Much of this material has already begun to arrive onsite and will begin going into place soon. Behind Brickbottom Condominiums there will continue to be a flurry of activity as ramps, walls, drainage, viaduct, and Community Path work converge.

Night Work: Yes. Near Brickbottom, expect installation of conduit on the Community Path to take place the weekend Oct. 2 – 5 during a track outage. A second shift will resume wall work in this area later in the month. Most of the noise generated with be from heavy equipment movement in the area.

Lechmere Viaduct and Charles River Dam Road

Green Line service between Lechmere and North Stations was suspended for approximately 1 year on May 24, 2020, to remove, rebuild, and relocate a section of viaduct and construct a new Lechmere Station. Replacement bus service is being provided for this duration.

See the Lechmere Viaduct and Charles River Dam Road page for more details.
