Longfellow Bridge, August 7, 2013MassDOT will close the Longfellow Bridge to all motor vehicle travel, except MBTA buses, on the weekends of Saturday-Sunday, October 26-27 and Saturday-Sunday, November 2-3.  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 this 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.

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. On Saturday, October 26, there will be alternating single lane closures on Memorial Drive eastbound to accommodate work above the roadway. Pedestrian travel will also be temporarily detoured from the eastbound side of Memorial Drive to the westbound side that day.

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, show on this detour route map.

The Longfellow Bridge, which connects Boston and Cambridge over the Charles River, is being rehabilitated as part of a three and a half year, $255.5 million effort funded through the Patrick Administration’s Accelerated Bridge Program. Rehabilitation of the iconic “salt and pepper” Longfellow Bridge will improve structural integrity and capacity, meet modern codes, including ADA accessibility, and create a safer configuration for more modes of travel.
