The new 589' structure includes a 255' main span with 132'-7" and 201'-7" side spans. The bridge was built using a combination of cast-in-place balanced cantilever and cast-on-falsework construction methods. Typical segments measured 14'-8" long by 31'-4" wide at deck level and 16' wide at the webs. The western cantilever required one of the form travelers to follow a horizontal curve with a 185' radius while remaining on the narrow box deck. After closure of the superstructure spans, a pedestrian walkway composed of 15'-10" wide by 6" thick precast panels was suspended from the soffit of the box using steel hanger rods spaced every 8'.
The contract for the replacement bridge was awarded in July of 2007. Removal of the steel truss bridge began shortly afterward. The first segment was cast in August 2008, and final closure was made in May 2009. The bridge accommodates two 10' traffic lanes and two 4' shoulders on the box girder deck.
