John Kilpatrick Turnpike Bridge Rehabilitation & Widening Over North Canadian River

  • Client: Oklahoma Turnpike Authority
  • Project Type: Structural Design, Roadway Design, Traffic Engineering


About this Project

The Oklahoma Turnpike Authority (OTA) proposed a bridge rehabilitation and widening project on the John Kilpatrick Turnpike (JKT) in Canadian County, Oklahoma. There are four bridges contained in the project including two bridges located at the North Canadian River and two overflow bridges located south of the river bridges.  The primary objective of the project is to widen all four bridges from the current four-lane divided section to a six-lane section.  Similar to the design we employed on the previous widening of the JKT in north Oklahoma City, the proposed project will widen all bridges and approaches by closing the gap in the existing 46’ wide median.  Another primary objective of the project is to rehabilitate the existing bridges.  The bridges currently have an extremely poor ride on the deck surfaces in many or all the spans on each bridge.  This project will remedy the poor ride making the driving surfaces of all four bridges follow a true and uniform design grade.  In addition, other rehabilitation will be conducted on the bridges as necessary to protect and extend the life of all four bridges well into the future.
