Replacement of Bridges Carrying Interstate 84 East and West over Marion Avenue in the Town of Southington
 
 
The Connecticut Department of Transportation is announcing that physical work is starting for the replacement of bridges carrying I-84 East and West over Marion Avenue in Southington.  The project is utilizing Accelerated Bridge Construction (ABC) methods to minimize construction time and inconvenience to the traveling public. 
 
This project consists of the superstructure replacement of Bridge Nos. 01235 & 01236, which carry Interstate 84 over Marion Avenue in Southington.   The proposed construction will be performed using accelerated construction methods. The new superstructures will be prefabricated on site in staging areas adjacent to the bridges. I-84 mainline and Marion Avenue traffic will remain open during the entire prefabrication period using only temporary lane closures for other work associated with the bridge work. Upon completion of the prefabrication of the new superstructures, I-84 eastbound and westbound at exit 30 and Marion Avenue under the bridges will be closed for one weekend (expected in or around June 2014).  The prefabricated superstructures will be moved from the staging areas using Self Propelled Modular Transporters (SPMTs) to replace the existing superstructures.  The existing bridges will be removed and new structures will then be set into place. 
 
The existing structures were built in 1963 and are single span structures that consist of a concrete deck slab on prestressed girders.  The new structures will be of a similar design however the vertical clearance on Marion Avenue under the bridges will be increased based on evidence of impact damage on the fascia girders.  The existing vertical clearances are 21 feet 8 inches (21'-8") at the eastbound structure and 15 feet 10 inches (15'-10") at the westbound structure.  The proposed vertical clearances over Marion Avenue are 22 feet 2 inches (22'-2") at the eastbound structure and 16 feet 4 inches (16'-4") at the westbound structure.
 
DOT Project No. 0131-0194/0195 was awarded to Northern Construction Service, LLC at a cost of $6,031,429.40 on June 7, 2013 and is scheduled to be completed July 2014.  The project is being administered by the Departmentís Office of Construction, District 1 Rocky Hill.
