The road, located in northwestern Palo Pinto County west of Graford, was authorized in 1945 to provide access to a former section of Possum Kingdom State Park.

[2] The highway travels in close proximity to Possum Kingdom Lake's southern shore, before reaching FM 2951.

Leaving Pickwick, PR 36 travels away from the lake, ending at SH 16, about 10 miles (16 km) west of Graford.

[3][4] PR 36 was originally designated in 1945 over an approximately 3.2-mile (5.1 km) segment connecting a former portion of Possum Kingdom State Park to SH 16.

The final 0.8-mile (1.3 km) extension to the current western terminus at the organizational campgrounds was added in 1947.
