Longfellow Bridge Rehabilitation Project Cambridge Bound Vehicle Detour in Effect
On July 20, 2013, the Massachusetts Department of Transportation (MassDOT) began major construction on the Longfellow Bridge, which connects Boston and Cambridge over the Charles River. Effective through September 2014, one lane of traffic will carry vehicles into Boston (using 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. 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.
Subsequent to September 2014, the Boston-bound travel lane will shift its position on the bridge while keeping the Cambridge-bound detour in place. 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.
The Longfellow Bridge Rehabilitation Project is part of the Patrick Administration’s $3 billion Accelerated Bridge Program.
