The State Highway 79 Bridge at the Red River is a bridge carrying Texas State Highway 79 and Oklahoma State Highway 79 over the Red River at the Texas-Oklahoma state line. The camelback pony truss bridge is 2,255 feet (687 m) long and has 21 truss spans. The Texas and Oklahoma highway departments built the bridge as a combined project in 1939. The bridge provided a direct route between Waurika, Oklahoma and Byers and Wichita Falls in Texas. The bridge is now the only camelback pony truss bridge remaining on a Texas state highway and is the fourth-longest truss bridge in the Texas state highway system.
