Charles River Accelerated Bridge Program

Longfellow Bridge

The Massachusetts Department of Transportation (MassDOT) is overseeing the reconstruction of the bridges in the Charles River Basin between Boston and Cambridge over the next 8 years.

The Accelerated Bridge Program (ABP) is the Commonwealth’s eight-year, $3 billion program to repair bridges across the Commonwealth that are currently structurally deficient or would otherwise become structurally deficient during the next eight years. As part of the recent transportation reform legislation, ownership of the bridges in the Charles River Basin has been transferred from the Department of Conservation and Recreation (DCR) to the newly created MassDOT. MassDOT is now responsible for the design and construction of bridges in the Charles River Basin that are included in the ABP program.

Bicycle/Pedestrian Path Access

As part of the Accelerated Bridge Program, MassDOT has hired a consulting team to conduct a Bicycle/Pedestrian Path Access Study to address connections from neighborhoods, institutions, and business districts to and from the path network along the Charles River Basin. The consulting team will make recommendations on bicycle and pedestrian designs for each of the bridges and intersections on each side of the bridges, as well as improvements to the path network itself.
