Pedestrian Bridge Construction
MassDOT has begun construction of the new pedestrian bridge connecting the Esplanade with Charles Circle. Work started on the Esplanade side of Storrow Drive to the west of the existing bridge. WSC will construct the new bridge during daytime hours from 7:00 AM to 5:00 PM. Periodic lane closures on Storrow Drive will be necessary to protect public safety. Closures for materials delivery and to move equipment will be scheduled for off-peak travel times to minimize traffic impacts. Vibration monitors will be placed near structures closest to the construction and noise will be monitored as necessary. The old pedestrian bridge will remain in service until the new one is complete, which is scheduled for 2017. View the Pedestrian Bridge Construction advisory for more information.
Modified Stage 2 Construction
In November, MassDOT's contractor, White-Skanska-Consigli (WSC), shifted traffic on the downstream side of the Longfellow Bridge to accommodate modified Stage 2 construction of the temporary outbound Red Line track (called a “shoo-fly”) on the roadway. WSC began the work early to advance the schedule and minimize the risk of delays due to winter weather. Stage 2 will last approximately three months, through January 2016. During Stage 2, WSC will also close the Longfellow Bridge to all vehicular traffic overnight. Details about the traffic shift and overnight closures are below. View the Modified Stage 2 Graphic for new travel space configurations. Visit the Traffic Information page for weekly updates on lane closures and details on other traffic management activities, including detour routes, during the current construction phase.
Temporary Traffic Shift
The Red Line "shoo-fly" track construction requires temporarily narrowing the 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 continue to use a dedicated lane on the roadway, which has been shifted to the east away from the MBTA Red Line tracks. Inbound vehicles have also been shifted to the east, so the temporary tracks can be installed. Outbound bikes and pedestrians now share the sidewalk. Bicyclists are asked to walk their bikes across the bridge to ensure the safety of all users, and signs are posted noting this requirement. 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.
Overnight Bridge Closures
Overnight closures of the Longfellow Bridge help expedite construction of the “shoo-fly”. Boston-bound vehicles should use the inbound detour routes described on the Traffic Information page. Bike and pedestrian travel 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.
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.
