Project schedule update – project anticipated to be complete by end of January

Based on the scope of repairs, inclement weather, and the need to coordinate with other projects, MassDOT has revised the schedule such that bridge work will now be complete by the end of January 2026. Crews will carry out construction activities on the underside of the bridge during overnight hours on Sunday through Thursday, from 11:00 PM each night to 5:00 AM the following morning, through the end of January. There are no further anticipated construction activities after this date for the Richmond Street Bridge Preservation Project.
