The Oklahoma Department of Transportation (ODOT) desired to replace the existing US-277 bridge over Smith Creek approximately two and one half (2 ½) miles west of the US-277 and US-81 junction in Grady County. The project is located west of Ninnekah, Oklahoma in central Grady County in a rural area. It was ODOT’s desire to build the new span bridge structure on an offset alignment to the north of the existing bridge, which will require some roadway modifications to US-277. Additionally, with the recent increase in heavy traffic volumes, the amount and severity of traffic accidents along the US-277 corridor had increased. Therefore, these roadway modifications included both horizontal and vertical roadway profile corrections as well as widening the roadway width.
