Route description

SH-20 begins just north of the

US-169

freeway.

SH-20 splits from US-169 north of

Pryor. West of Salina, the highway bridges Lake Hudson. In Salina, SH-20 meets SH-82

, with which it begins a concurrency.

Headed north from Salina, the two highways begin to cross some mountainous terrain. The highways provide access to

US-59/State Highway 10 through Jay

. SH-20 then splits off to the east, running 11 miles (18 km) to the Arkansas line.

The easternmost miles run north/south along the Oklahoma–Arkansas state line, and along this stretch the highway

Highway 43. The highway continues northward into Missouri at the point where the Oklahoma, Arkansas and Missouri borders meet, and thereafter becomes Missouri Route 43

.

History

On April 10, 2008, a section of SH-20 in Rogers County near Keetonville, west of Claremore, was closed due to a landside caused by heavy rains.^[2] A 500-foot (150 m) section of roadbed was washed away, forming a large crack in the pavement and damaging the guardrail.^[3] The highway was re-opened June 5, 2008 after being repaired.
