Beggs–Sapulpa alternate route

U.S. Highway 75 Alternate
Location	Beggs–Sapulpa, Oklahoma
Length	30.15 mi (48.52 km)

Main article: U.S. Route 75 Alternate (Beggs–Sapulpa, Oklahoma)

U.S. Route 75 Alternate, the only such special route stemming from U.S. 75, is a former alignment of the mainline highway from east of Beggs to Sapulpa, Oklahoma, a suburb of Tulsa. The route is 30.15 miles (48.52 km) long.^[1][2] U.S. 75 Alternate is also sporadically signed as U.S. 75A and State Highway 75A.

The highway begins at U.S. 75 east of Beggs and travels west to that town, where it turns north. It runs through the towns of Mounds and Kiefer before reaching Sapulpa. In Sapulpa, its northern terminus is explicitly signed at an intersection with State Highway 66 and other state highways, but official Oklahoma Department of Transportation maps show it extending northeast along SH-66 until the point where it merges with I-44.

U.S. 75 followed what is now U.S. 75 Alternate prior to 1959. On August 28 of that year, mainline U.S. 75 was rerouted onto the new Okmulgee Beeline freeway and expressway, and U.S. 75 Alternate was established along the former route of the highway.
