July 26 through August 11: MassDOT will replace westbound side of the bridge
Intensive construction operations will mean significant travel impacts throughout the region
BOSTON – The Massachusetts Department of Transportation (MassDOT) is reminding members of the public that significant travel impacts will begin next week as part of the intensive construction operations to replace the westbound side of the Commonwealth Avenue Bridge.
On the evening of Thursday, July 26, a section of Commonwealth Avenue and the Boston University Bridge will be closed to vehicular traffic, and MBTA bus detours for the CT2 and 47 routes will go into effect. The MBTA Green B Line will be replaced by shuttle buses at the start of service on Friday, July 27, and lane reductions on I-90 in Boston will then begin later that evening.
Crews will start demolishing the westbound side of the bridge on the morning of Saturday, July 28. The MBTA Commuter Rail Worcester/Framingham line and the Amtrak Lake Shore Limited line will be replaced by bus shuttles throughout the weekend, and during the following weekend, in order to ensure adequate room for operations. The new westbound side of the bridge will then be constructed with steel beams, prefabricated concrete deck panels, and asphalt by August 11.

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 will be constructed this summer using 3 cranes that weigh 600 tons each. Crews will utilize 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 upcoming travel impacts will be as follows:
Pedestrians and Bicyclists
Pedestrians and bicyclists will have access across the Commonwealth Avenue Bridge on the eastbound side throughout construction.
Download the Blue Bikes app on the App Store or Google Play to find a station near you. For a limited time, Blue Bikes is dropping their Single Trip Pass to $1 from July 26 – August 11, available in the Blue Bikes app.
MassDOT is also partnering with the City of Boston to provide an additional temporary Blue Bikes station at Silber Way on Commonwealth Ave during the construction period.

MassDOT asks for the community’s help to reduce traffic volume in the area as much as possible. MassDOT encourages the public to consider:
- REDUCE – Work with employers on flex time or telecommuting as an alternative to travel during this time period. Take your summer vacations during this time and avoid traveling through the area if at all possible
- REROUTE – Plan alternative travel routes around this construction area during the times mentioned.
- REMODE – Consider using alternate modes of transportation which may include public transit, walking or biking.
The Baker-Polito Administration appreciates the cooperation and patience of the traveling public as core transportation infrastructure is improved. Members of the public are encouraged to utilize the appropriate technology tools including mass511.com, our GoTime travel app, and other wayfinding resources to find the most appropriate route, mode, and timing of travel during our construction operations.
Individuals are encouraged to sign up for email notices to receive public meeting notices, construction updates and traffic alerts.
