Work on the Clayton Street bridge in Dorchester, which services the MBTA’s Red Line, will begin soon, according to T officials.
Residents in the area can expect the project, which will run from now until Feb. 2014, to cause some street detours and a delay in T service.
First constructed in 1911, the three-span steel structure needs its abutments retrofitted and its superstructure replaced.
At a past meeting T officials said the life-space for a bridge similar to Clayton Street’s is about 70-years.
The project will cost an approximate $5.5-million and the contractor will be the Canton-based Barletta Heavy Division.
In addition to the replacement of the bridge, work also includes the reconstruction of the sidewalks and roadway that runs underneath the bridge. The roadway will be lowered to increase clearance to 14-feet and the steel bents on the curb line will be eliminated to improve pedestrian access.
The biggest interruptions to traffic and T service will be from March to December.
From March until May crews will begin the construction of a temporary utility bridge. That work is expected to cause no interruption to T service and will only cause minimal roadway closures.
On the weekend of May 25 to May 27 Clayton Street will be closed while abutment tiebacks are installed. There will be no interruption to T service during this work.
On the Jul. 13, Jul. 20, and Jul. 27 weekends T service will be replaced with buses as the abutment micropiles are installed. This work is expected to cause minimal interruption to street traffic.
During the long weekend of Oct. 11 to Oct. 14 the bridge will be removed and replaced. During that time T service will be replaced with buses and both Clayton Street and Dickens Street will be closed.
Finally from Oct. 15 to Dec. 10 crews will reconstruct the roadway and sidewalks and reconstruct and remove the temporary utility bridge. That work is expected to cause some traffic restrictions and sidewalk closures.
Heavy work on the bridge is expected to come to a close by December 2013 with the work completely done by February 2014.
