Chelsea Street Bridge 2012The new bridge carrying Chelsea Street over the Chelsea Creek at the Boston/Chelsea line is scheduled to reopen to traffic on Saturday, May 12. 

Construction crews are completing the last of the major work items necessary to allow the opening of the new bridge.  On March 15th, MassDOT projected the bridge would be ready for reopening in late April.  As final work continued, crews encountered unforeseen conditions associated with the complex underwater operations.  In addition, the schedule for the related channel dredging work being completed by the Army Corp of Engineers was delayed by the need to remove an abandoned sewer line beneath the bottom of the channel.

Final work items will continue after the bridge is opened to traffic on May 12, requiring overnight closures during May and early June that will not affect weekday commuter traffic.  Additional work will be completed during the day after the morning commute with at least one lane of traffic open in each direction. 

The historic $125.3 million project will improve the efficiency and operation of the bridge for vehicle traffic and for critical maritime vessels to safely navigate the channel.

MassDOT appreciates the continued patience that those affected by the closure of the bridge and the construction activities have shown throughout the duration of the project.
