Boston: Turnpike/I-90 at Comm. Ave.: Lane restrictions this weekend


MassDOT’s ongoing project to rebuild the foundation of the bridge carrying Commonwealth Avenue over the Turnpike will require additional lane closures that will affect travel on the Turnpike this weekend.

Beginning tonight, Friday, Jan. 16, at 10 p.m., the two left lanes in both directions on the Turnpike will be closed to drivers. These closures will be in effect overnight, until 9 a.m. on Saturday, Jan. 17.

At that time, the two-lane closure will be reduced to one lane in both directions, from 9 a.m. to 10 p.m.

Beginning at 10 p.m. on Saturday, Jan. 17, the closure will be expanded back to the two left travel lanes in both directions. This will be in effect overnight until 9 a.m. on Sunday, Jan. 18, when the two-lane closure will be reduced to one lane.

This setup will be repeated on Sunday, Jan. 18, at 10 p.m. and will be in place until 5 a.m. on Monday, Jan. 19. Effective Monday, standard nightly closures of a single lane will be in place for the remainder of the week.

These lane closures are in addition to the existing work zone setup, which for the duration of this phase has reduced the Turnpike from the west end of the Prudential Tunnel to the Commonwealth Avenue overpass to three lanes from four.

Drivers should reduce speed when traveling through a work zone and should expect delays caused by the additional lane restrictions.

The lane closures are necessary to rebuild the foundation of the 50-year-old bridge that carries Commonwealth Avenue over the Turnpike and the railroad corridor. The $22.3 million effort is the precursor to the reconstruction of the structurally deficient Commonwealth Avenue bridge deck that carries surface traffic and the Green Line over the Turnpike and railroad.
