Beginning on July 20, 2013, the Massachusetts Department of Transportation (MassDOT) will begin major construction activity on the Longfellow Bridge (State Route 3), which connects Boston and Cambridge over the Charles River. As part of the rehabilitation project, the bridge will be closed for vehicular travel in the Cambridge-bound direction. This three and a half year project will rehabilitate the iconic “Salt and Pepper” Bridge to improve structural integrity and capacity, meet modern codes (including ADA accessibility), and create a safer configuration for all bridge users.
One vehicle travel lane to Boston, MBTA Red Line service inbound and outbound, emergency response, and bicycle and pedestrian access will be maintained throughout construction.
Effective July 20, 2013 through September 2014, one lane of traffic will carry vehicles into Boston (using the current Cambridge-bound lane) and Cambridge-bound traffic will be detoured using a signed route from Charles Circle to Land Boulevard using Leverett Circle and Monsignor O’Brien Highway (detour route map is attached).
Subsequent to September 2014, the Boston-bound travel lane will shift its position on the bridge while keeping the Cambridge-bound detour in place.
Preliminary work to prepare for construction and the traffic shift began in April 2013 and will be completed by July 20. Traffic signal timing changes, lane restriping, and curb modifications at five area intersections will accommodate the traffic management plan. Overhead highway signs on I-93 and I-90 and portable variable message boards on local roads will provide advance notice of traffic pattern changes. Traffic conditions will be monitored at key locations and through the use of traffic cameras installed as part of the project.
A public meeting to present details on this detour route is scheduled for Wednesday, July 10, 2013 from 7 to 9 PM at MIT, Building E 25, Room 111 (E25-111), 45 Carleton Street, Cambridge. The detour route can also be found through http://www.massdot.state.ma.us/Portals/26/docs/Longfellow/DetourRoute_CB_rev.pdf.
The Longfellow Bridge Rehabilitation Project is part of the Patrick Administration’s $3 billion Accelerated Bridge Program. For more information on the project and traffic management plans, visit the website at www.mass.gov/massdot/longfellowbridge.
