Lechmere Station

Overview of current work in the area: Besides building a new Lechmere Station on the north side of Monsignor O'Brien Highway, work in this area includes constructing an elevated viaduct that will connect to the existing structure running along Charles River Dam Road. After the Lechmere Station stop, the viaduct continues behind buildings along O'Brien Highway until it splits, with one leg heading to Union Square and the other north to the future East Somerville Station.

Work Schedule: Monday – Friday, 7 a.m. to 4 p.m. with some weekends

Work Planned for the next two weeks: Foundation work for the new Vehicle Maintenance Facility near the existing Boston Engine Terminal will move forward with pile driving occurring daytime hours throughout the week from early/mid July through late August. Expect increased noise from this operation.

Closer to O'Brien Hwy., residents will continue to see drilling and pouring concrete for foundations which will support the viaduct. To this end we are now drilling foundations near the existing viaduct and adjacent to properties on Leighton St. and marking utilities.

Building elevated foundations for the viaduct will also continue in the Boston Engine Terminal (BET) area near Brickbottom Condominiums.

Night Work: Since work in the Boston Engine Terminal area is adjacent to or over existing commuter and freight rail track, work will often be performed at night and and on weekends during outages..

East Somerville Station (Fitchburg St. to Walnut St.)

Overview of current work in the area: Widening the rail overpass at Washington St. and drainage improvements are key aspects of work in this area. As you go from Washington St. and head north toward Walnut St. sound wall posts have been installed on the east side of the alignment between McGrath Hwy and Walnut St. Panels will be placed later this summer once grading is completed. Later this year the commuter line track will shift to the east side.

Work Schedule: Monday – Friday, 7 a.m. to 4 p.m. with some weekends

Work Planned for the next two weeks: Closer to Fitchburg St. and near Inner Belt Road, workers are welding together 80 ft. long sections of light-rail (1,700 tons total) that will be placed along the alignment next spring. In the near term we will be placing an additional 175 tons of commuter grade rail line this fall along the east side of the corridor.

At the Washington St. overpass drainage installation and construction of new north and south abutments continues.
