SH 4 over I-40

Client: Triad Design Group

Owner: Oklahoma Department of Transportation

Located in Yukon, Oklahoma, the existing twin steel I-beam bridges were replaced with a simply supported 4-span (59′-117′-117′-59′) steel plate girder bridge, that was built in two (2) phases. The new bridge accommodates six (6) lanes of traffic, including two (2) dedicated turn lanes to better facilitate the increased traffic in the area. Sidewalks were included for pedestrian use and Osage Peace Shields were added for aesthetic value.
