Pryor Creek Bridge was built in 1926 and carried U.S. Highway 66 traffic from 1926 to 1932, when a new alignment of Route 66 bypassed it. The bridge is 123 feet long and 19 feet wide, with a modified Pratt through truss design, and it was built by E.G. Fike and Son. In Oklahoma, it is the only remaining unaltered example of this design. Inscribed in the concrete on top of the southwest abutment is "Okla S.H.C. 1926," a reference to the Oklahoma State Highway Commission. Located in Chelsea, Oklahoma, it was added to the National Register of Historic Places on Sept. 6, 2006.
