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.
Upcoming MBTA Red Line Diversion Weekends – November 23/24
The Massachusetts Department of Transportation (MassDOT) will close the Longfellow Bridge to all motor vehicle travel, except MBTA buses, on the weekend of Saturday, November 23 through Sunday, November 24. The closures are to implement Red Line related work to prepare for bridge construction. Buses will replace Red Line trains for service between Kendall/MIT Station and Park Street Station, with a stop at Charles/MGH Station. The bus route and stops are shown on the following map.
Bus service will be in place for Boston and Cambridge-bound Red Line customers from the start of service on Saturday to the end of service on Sunday of each weekend. Red Line trains will resume service on Monday morning. The diversion is necessary for MassDOT’s design/build contractor, White-Skanska-Consigli JV, to perform work in close proximity to the Red Line tracks that is not allowed during MBTA service hours. Please visit the MBTA’s service updates webpage for additional information.
MBTA buses will be the only motor vehicles permitted on the bridge. All other motor vehicles including passenger vehicles, trucks and all other buses will need to use one of two routes shown on the detour map to reach Boston. One route uses Memorial Drive westbound to make a u-turn at Ames Street for access to Memorial Drive eastbound to Land Boulevard and Charles River Dam Road (Monsignor O’Brien Highway/Route 28) to reach Leverett Circle. A second route uses 3rd Street and Binney Street to reach Land Boulevard. Truck restrictions are in place for Memorial Drive. The Cambridge-bound detour remains in place 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.
Emergency response, bicycle and pedestrian access will be maintained across the bridge during the weekend diversions. Please note: Bicyclists will be asked to walk their bikes on the sidewalk across the Longfellow Bridge to ensure the safety of all bridge users.
