Longfellow Bridge, 2015Beginning on Monday, November 2, and lasting for three months, MassDOT’s contractor will shift vehicle, bike, and pedestrian travel spaces on the Longfellow Bridge to accommodate modified Stage 2 early construction of the Red Line temporary track on the downstream roadway.

From November 2, 2015 through January 2016, the Longfellow Bridge will be closed to all vehicular traffic overnight, Mondays through Fridays from 9:00 PM each night to 5:00 AM the following morning. The closure may extend to Saturday night, if needed. Bike and pedestrian access will be maintained at all times. For more information, read the Modified Stage 2 Advisory. View the Modified Stage 2 Graphic and the Stage 3 Graphic for new travel space configurations.

Temporary Traffic Shift

The work will require temporarily narrowing space for vehicles, bikes, and pedestrians on the downstream side of the bridge. The traffic shift is necessary to maintain two-way bike travel across the bridge until construction of the upstream side is complete and all bike travel is shifted to it.

While the temporary traffic shift is in place, inbound bikes will continue to use a dedicated lane on the roadway, which will be shifted to the east away from the MBTA Red Line tracks. Inbound vehicles will also be shifted to the east, so the temporary tracks can be installed. Outbound bikes and pedestrians will share the sidewalk. This configuration differs from the original Stage 2 plan where bike travel in both directions would have been shifted to the upstream side of the bridge for construction of the temporary track. It is an extension of what is currently in place in the middle of the bridge between the “Salt and Pepper” towers. Bicyclists will be asked to walk their bikes across the bridge to ensure the safety of all users, and signs will be posted noting this requirement.

Nightly Closures of the Longfellow Bridge to Vehicles

Overnight closures of the Longfellow Bridge will expedite construction of the shoo-fly. Boston-bound vehicles should use the inbound detour routes described below. Bike and pedestrian traffic will be maintained across the bridge at all times. No closures will be implemented within one hour before and after all events at TD Garden to minimize traffic impacts at Leverett Circle.

Inbound Detour Routes: All motor vehicles will be detoured using one of two routes. Passenger vehicles may use 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, or 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 and Charles River Dam Road (Monsignor O’Brien Highway/Route 28).

The Cambridge-bound detour remains in place using the existing signed route from Charles Circle following Charles Street to Leverett Circle, Monsignor O’Brien Highway (Route 28)/Charles River Dam Road and Land Boulevard.

Next Steps

In early February, once the temporary track is complete, all bikes will be shifted to the upstream side of the bridge and the outbound MBTA Red Line will be shifted to the temporary track. Inbound trains will be moved to the current outbound side and WSC will begin rehabilitating the bridge under the current location of MBTA inbound tracks. This Stage 3 work will take approximately eight months to complete. During this stage, inbound vehicles and pedestrians will continue to use the downstream side.
