The Dorchester Ave. Bridge Project has recently completed the steel girder erection phase of the project and continues moving forward with construction.  During the upcoming weekends from Friday night, June 07 through Monday, June 10, and Friday night, June 14 through Monday, June 17, the Project will be working continuously around the clock, during which time neighbors can expect increased construction activity resulting in noise and minor traffic inconveniences.

During this time, the bridge will continue to remain closed to vehicles, pedestrians, and cyclists. Therefore, as seen below, the vehicle and pedestrian detour maps remain in place.

The MBTA appreciates your patience and consideration while we work to complete this critical infrastructure project. To sign up for email updates please visit
