MBTA Red Line Weekend Diversions and Longfellow Bridge Closures January 2016

Work continues on the restoration and rehabilitation of the historic Longfellow Bridge.
Work continues on the restoration and rehabilitation of the historic Longfellow Bridge.

The Longfellow Bridge will be closed to vehicle traffic during each of the next four weekends, and Red Line service will be diverted to buses during the closures. The bridge will remain open for pedestrians. Please read the following press release from the Massachusetts Department of Transportation for more details, including suggested detour routes. – Tim.


MassDOT’s contractor, White-Skanska-Consigli JV (WSC), will implement a series of bridge closures and Red Line weekend diversions during January 2016. WSC will close the Longfellow Bridge to all vehicular traffic, except MBTA buses, from 11:00 PM on Fridays to 5:00 AM on Mondays. The closures are necessary to implement MBTA Red Line diversions that replace trains with buses. This will allow WSC to perform work in close proximity to the Red Line tracks to prepare for Stage 3 of construction. The schedule is as follows:

Longfellow Bridge Closures:
• Friday, January 8 – Monday, January 11
• Friday, January 15 – Monday, January 18
• Friday, January 22 – Monday, January 25
• Friday, January 29 – Monday, February 1

Red Line Weekend Diversions:
• Saturday, January 9 – Sunday, January 10
• Saturday, January 16 – Sunday, January 17
• Saturday, January 23 – Sunday, January 24
• Saturday, January 30 – Sunday, January 31

Bus service will be in place from the start of service on Saturdays to the end of service on Sundays. Buses will replace Red Line trains in both directions 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. All shuttle bus stops are accessible for people with disabilities. Red Line trains will resume service on Monday mornings. 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 Boston-bound routes to reach Charles River Dam Road (Monsignor O’Brien Highway/Route 28) and Leverett Circle.

Emergency response, bicycle, and pedestrian access will be maintained across the bridge during weekend diversions. Cyclists must walk their bikes on the sidewalk across the Longfellow Bridge in both directions to ensure the safety of all bridge users. Inbound and outbound bike lanes will be closed during this time to ensure cyclist safety. The Massachusetts Avenue Bridge and Dr. Paul Dudley White Bike Path across the Craigie Dam Bridge can be used as alternate routes to ride bicycles across the Charles River.

Boston-bound Detour Routes: 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.

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.

MassDOT encourages drivers to avoid the area and seek alternate routes to minimize delays. Those traveling through the area should expect delays and should reduce speed and use caution. The schedule for this major infrastructure project is weather dependent and subject to change without notice.

Traffic Advisory Reminder for Longfellow Bridge Rehab Project

Please see the following construction and traffic advisory from the Department of Transportation (MassDOT) – Tim.

“The previously announced traffic shift on the Longfellow Bridge will now begin on Monday, November 9. MassDOT’s contractor, White-Skanska-Consigli (WSC), will shift 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 is beginning 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, Mondays through Fridays. The closure will begin at 9:00 PM each night and end at 5:00 AM the following morning. The closure may extend to Saturday nights, if needed. The closure will be from November 9, 2015 through January 2016, and is necessary to expedite the work and shorten the duration of the temporary traffic shift.

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. View the Modified Stage 2 Graphic for new travel space configurations.

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 until 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

WSC held an emergency responder briefing on October 30 to discuss traffic management plans with Mass General Hospital and first responders, such as police and fire personnel. WSC has also coordinated with the MBTA to ensure access for emergency busing should an emergency shutdown of the Red Line be necessary.

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. View the Stage 3 Graphic for new travel space configurations.
