As part of the IH 39/90 South Segment team, KSingh was tasked with providing structural engineering for the replacements of the Woodman Road and Hart Road overpass bridges. The existing structures were lengthened to accommodate the ultimate typical section of the mainline interstate. The proposed structures included 2-span, pre-stressed girder bridges. The bridges were designed to be built in several stages which allowed for traffic to remain open in both directions on the mainline. The bridge replacements also included design of adjacent approach intersections.
