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 Union Square Station continues to take shape. Expect to see steel for the station going into place by mid-October. 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 frequent nights and weekends.

Work Planned for the next few weeks: Robust work continues between the Gilmore Bridge and the Fitchburg Viaduct where the elevated track splits towards the Union Square and Medford Branches. Only a few spans remain without the steel beams that will be placed overhead. Work is well underway preparing the viaduct decking for concrete pours above Leighton St. Deck work is in various stages throughout this entire section. Elevated work will also continue to advance on the Community Path.

Expect continued work both at ground level and track level on the new Lechmere Station. This includes steel placement for the station which is expected during this period.

Near Brickbottom Condominiums, work continues on the viaduct, various walls, and drainage structures. Some of this wall work is scheduled as overnight activity. Expect work in this area to remain extremely active for the next several months.

Night Work: Yes. Expect construction on walls in this area to occur for another few weeks followed by a pause in night work before resuming for a period in October. 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.
