North Washington Street bridge replacement

The following is an update from MassDOT concerning the North Washington Street bridge (Charlestown Bridge) replacement project. They are providing this update that includes information applicable through July 13. MassDOT will provide additional notices as needed for high-impact work and changes to traffic configurations beyond those described.


No work will take place on Thursday, July 4 in observance of Independence Day. Additionally, no lane closures will take place from Wednesday July 3 – Friday, July 5 to accommodate increased holiday traffic.


DESCRIPTION: Continued construction of the temporary pedestrian and utility bridge base, bents, and abutments. Work on the temporary bridge above the Tudor Wharf walkway requires some daytime closures of the walkway.

WORK HOURS: Daytime (6 a.m.–6 p.m.) on weekdays and Saturday, July 13.

TRAVEL IMPACTS: On weekdays during off-peak daytime hours (10 a.m.–2 p.m.), the inbound right lane will be closed to create a safe work zone. During the Tudor Wharf walkway closures, pedestrian access will be provided via the Water Street underpass and guidance signage will be provided.


DESCRIPTION: At the south end of the bridge at Keany Square, installation of a waterline by J.F. White continues as well as installation of a gas pipe by National Grid.

WORK HOURS:Daytime (7 a.m.–3 p.m.) on weekdays.

TRAVEL IMPACTS: Inbound traffic will be reduced to one lane on weekdays during off-peak hours (10 a.m.–2 p.m.). Outbound traffic will be reduced to one lane on weekdays during off-peak hours (7 a.m.–2 p.m.) at Keany Square. All turn movements will be maintained, with two inbound lanes available during the morning peak hours.


MassDOT has begun work on the Tobin Bridge/Chelsea Curves Rehabilitation Project which requires significant traffic impacts including 24/7 lane closures. For information or to sign up for project-specific construction look-aheads like this one, visit the project website.

PEDESTRIANS AND CYCLISTS: The bridge’s eastern sidewalk is open and available to all pedestrians and cyclists with crossings at both Keany and City Squares. Please be advised that the DCR-controlled Charlestown locks can provide another alternate route, but may close without warning and beyond control of this project.

All users should take care to pay attention to all signage and police details and move carefully through the work zone. Police details, lane markings, temporary barriers, traffic cones, signage, and other tools will be used to control traffic and create safe work zones.

The contractor is coordinating with the TD Garden and local police to provide awareness and manage traffic impacts during events. For your awareness, during this look-ahead period, there are no events scheduled at the TD Garden.
