The Wanette–Byars Bridge is a long bridge in central Oklahoma. It crosses the Canadian River between Byars in McClain County and Wanette in Pottawatomie County. The bridge is on a county road, not a state-designated highway. The bridge was built in 1902 by the American Bridge Company to serve as a rail bridge connecting Pauls Valley with Shawnee. It was later converted to a one-lane bridge for auto traffic. The bridge is of the camelback truss design and is composed of three spans, each 265 feet (81 m). Each of these spans are the longest in Oklahoma.
