Effective July 21, 2013 through September 2014, one lane of traffic will carry vehicles into Boston (using the former Cambridge-bound lane) and 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.
The 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.
