Buses Replace Commuter Rail, Amtrak This Weekend Due to Comm Ave Bridge Project

The following is a press release from MassDOT. It is published as received


The Massachusetts Department of Transportation (MassDOT) has announced that work is on schedule on the project to replace the westbound side of the Commonwealth Avenue Bridge as significant travel impacts are in place throughout the Boston region.

I-90 in Boston will have two lanes of travel in each direction until 8 p.m., when I-90 westbound will be reduced to one lane of travel. This configuration will remain in place until approximately 5 a.m., Monday, August 6, when I-90 is restored to its full capacity of four lanes of travel in each direction. Off-peak and overnight lane closures will continue to be necessary throughout the coming weeks as crews conduct finishing work.


“Members of the public should be aware that if they are heading out of Boston tonight or throughout the weekend, only one lane of travel will be open on I-90 westbound after 8 p.m., and until 5 a.m., Monday.” said Highway Administrator Jonathan Gulliver. “We expect to restore the Mass Pike to its full capacity for peak travel hours by Monday morning, and we appreciate members of the public continuing to heed our warning on driving through this area and making smart decisions on route, timing, and mode of travel.”

Work is progressing so that the standard closure of Memorial Drive in Cambridge to vehicular travel is expected to be in place on Sunday, August 5. This closure takes place from 11 a.m., to 7 a.m., between Western Avenue and Mount Auburn Street.

Last night, crews began removing the existing steel beams on the final span of the Commonwealth Avenue Bridge and continued installing closure pours, which are pours of concrete that seal in precast deck panels. These closure pours will continue throughout the day along with work on the concrete backwall and utility operations. Crews today will also be completing demolition activities and beginning to place steel beams on the final span of the bridge.

This $110 million bridge replacement project, which would take an estimated four to five years using conventional techniques with significant lane-takings and service disruptions, is scheduled for completion in 2019 under the accelerated plans. The westbound side of the bridge is being constructed this summer using 3 cranes that weigh 600 tons each. Crews are utilizing this equipment to put in place 45 steel beams and 214 pre-fabricated concrete deck panels along with 680 cubic yards of concrete and 520 tons of hot mix asphalt.

The full travel impacts are as follows:
