From Saturday, August 1 to Friday, August 21, MassDOT will periodically close the Longfellow Bridge to all vehicular traffic. Boston-bound vehicles will use one of two detour routes to reach Charles River Dam Road (Monsignor O’Brien Highway/Route 28) and Leverett Circle. Bike and pedestrian traffic will be maintained at all times. Passenger vehicles may use one of two routes 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. Height restrictions are in place for Memorial Drive, so all buses and trucks must use 3rd Street and Binney Street to reach Land Boulevard. View the Longfellow Bridge Closures – August 2015 Advisory for more information about closure hours during this work.
From Monday, August 3 through Friday, August 7, the contractor may implement single lane closures on Storrow Drive west and eastbound in the vicinity of the Longfellow Bridge during the daytime hours of 9:00 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.
