Traffic Management through April 29

Lane Closures

  • Storrow Drive east and westbound - Monday, April 24, through Friday, April 28 - single lane from 9:00 PM to 11:00 PM, double lane from 11:00 PM to 5:00 AM
  • Memorial Drive east and westbound, single lane - Monday, April 24, through Friday, April 28 - 9:00 PM each night to 5:00 AM the following morning
  • Memorial Drive east and westbound, alternating single lane - Monday, April 24, through Saturday, April 29 - 9:00 AM to 3:00 PM
  • Storrow Drive east and westbound, alternating single lane - Monday, April 24, through Friday, April 28 - 10:00 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.

Longfellow Bridge Closures

MassDOT will close the Longfellow Bridge to all vehicular traffic as follows:

  • There are no bridge closures scheduled through April 29

Bike, pedestrian, and MBTA Red Line travel will be maintained. Bicyclists, both inbound and outbound, should share the upstream sidewalk with pedestrian traffic during this timeframe. Boston-bound vehicles should use the inbound detour routes described below.

The schedule for this major infrastructure project is subject to change without notice. No closures will be implemented within one hour before and after all events at TD Garden or Fenway Park to minimize traffic impacts in the area. 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. Emergency response, bicycle and pedestrian access, and MBTA Red Line service will be maintained across the bridge during construction.

Detour Routes

Boston Bound Traffic

When the Longfellow Bridge is closed to vehicular traffic, Boston-bound vehicles should use one of two inbound detour routes to reach Charles River Dam Road (Monsignor O'Brien Highway/Route 28) and Leverett Circle. Height restrictions are in place for Memorial Drive, so all buses and trucks must use the 3rd Street to Binney Street detour described below.

  • From Main Street, turn right onto Memorial Drive westbound, and make a U-turn at Ames Street to access Memorial Drive eastbound. Follow Memorial Drive eastbound to Land Boulevard and turn right onto Charles River Dam Road (Monsignor O'Brien Highway/Route 28) to reach Leverett Circle.
  • From Broadway, turn left onto 3rd Street, turn right on Binney Street, turn left onto Land Boulevard, and then turn right onto Charles River Dam Road (Monsignor O’Brien Highway/Route 28) to reach Leverett Circle.

Cambridge Bound Traffic

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 Cambridge 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.

Anderson Memorial Bridge

The Massachusetts Department of Transportation (MassDOT) will be making a traffic shift change required for Phase 3 of the Anderson Memorial Bridge Rehabilitation Project starting on the morning of Friday, May 8, 2015.

During phase 3 of the project, MassDOT's contractor will be demolishing and rebuilding the west side of the Anderson Memorial Bridge, which carries traffic over Charles River between Boston and Cambridge. To accommodate this work, traffic will be directed onto the newly constructed east half of the bridge. The traffic shift will be done in phases. During the traffic shift, one lane of travel in each direction will remain open along with a pedestrian sidewalk.

Once the traffic shift has been completed, the westerly sidewalk will be closed and traffic will be reduced to one lane in each direction on the east side of the bridge. Pedestrians will need to use the easterly sidewalk and bicyclists will need to share the current eastbound and westbound lanes. The left hand turn restriction will remain in place at Memorial Drive and JFK Street.
