About This Project


MassDOT is undertaking the Longfellow Bridge Rehabilitation Project, one of five major projects of the Commonwealth's $3 billion Accelerated Bridge Program. The historic bridge, with its iconic "salt and pepper" towers, is a vital link between Boston and Cambridge, making important regional connections and contributing to the Charles River Basin Historic District.

The project will address the bridge's current structural deficiencies, upgrade its structural capacity and bring it up to modern code, including improving multi-modal access and bridge-to-city-street connections to meet accessibility guidelines. The repairs and modifications will be consistent with the historic character of the bridge and comply with environmental standards.

Construction Updates

Longfellow Bridge Construction

All modes of travel in each direction were shifted to their final configuration on May 31, 2018. Substantial Completion will be reached in fall 2018 and Final Completion at the end of 2018. The contractor is currently completing assorted tasks in preparation for substantial completion.

Pedestrian Bridge Construction

MassDOT began construction of the new Frances "Fanny" Appleton bridge connecting the Esplanade with Charles Circle in November 2015. Work started on the Esplanade side of Storrow Drive to the west of the existing bridge. To expedite work, the contractor installed the concrete footings in late 2016/early 2017 when crews were available. Steel arches and beams were installed in fall 2017 and work will continue through summer 2018. The old pedestrian bridge will remain in service until the new one is complete, which is scheduled for Fall 2018.
