The Chelsea Street Bridge project continues in early 2012 with the new vertical lift structures and concrete bridge deck now completed and in place. Current work, seen at left, includes demolition of piers from the old bridge under the new structure.
To allow for the final work on this historic $125 million MassDOT project, the Chelsea Street Bridge over Chelsea Creek at the Boston/Chelsea line remains closed with detours in place.
The Chelsea Street Bridge project involves the replacement of a truss-type structure that spans 450 feet and will provide 175 feet of vertical clearance when raised. The new bridge will include four lanes of traffic and two pedestrian sidewalks.
This is the largest permanent lift bridge built in Massachusetts to date. To accommodate the massive size and tight space constraints in the bridge area, MassDOT contractors used an innovative technique of launching the truss across the river. The launching sequence of the truss bridge across the channel was carefully designed to minimize disruption of the navigation channel below. This launch process was completed in November 2011.
After the launch was successfully completed, the project moved to the concrete pours of the 450 foot long bridge deck, which required the project to enclose and heat the bridge structure because of colder early winter weather. The concrete pours were completed in late December 2011.
Project work now includes removing the old bridge piers below the new bridge. The contractor is making significant progress and working seven days a week and 24 hours a day to remove the 5 piers, which include segments up to 40 feet below the river bottom. Work on the bridge itself includes installation of bridge joints, barrier, and other safety items.
It is anticipated that all required work will be complete and allow a bridge opening to traffic by the end of April. MassDOT will announce publicly an exact opening date in advance.
