There will be no lane closures from 5:00 AM on Friday, September 4 through 5:00 AM on Tuesday, September 8 for the Labor Day holiday weekend.
From Tuesday, September 8 to Friday, September 11, the contractor may implement single lane closures in the vicinity of the Longfellow Bridge as follows:
- Storrow Drive westbound - 9:00 AM to 3:00 PM
- Memorial Drive eastbound - 7:00 AM to 3:00 PM
The lanes closed and time of closure will vary depending on the activity taking place. The closures are necessary to allow for deliveries and to protect public safety when construction activities are taking place on the bridge above the roadway.
The schedule for this major infrastructure project is subject to change without notice. All lane restrictions and closures and construction activities are weather dependent. As is typical with most large construction projects, work may sometimes take place without prior notice; however, MassDOT will make every effort to provide advance notice.
In the current construction phase, one lane of traffic carries vehicles into Boston (using the former Cambridge-bound lane), except on MBTA Red Line diversion weekends. For the duration of the project, all Cambridge-bound traffic is being detoured using a signed route from Charles Circle following Charles Street to Leverett Circle, Monsignor O'Brien Highway/Charles River Dam Road and Edwin H. Land Boulevard. To learn more please review the detour route map. An alternate detour route uses Storrow Drive westbound to the Massachusetts Avenue Bridge. Please note: Storrow Drive and Memorial Drive have truck restrictions.
Emergency response, bicycle and pedestrian access, and MBTA Red Line service will be maintained across the bridge during construction.
