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.
