Route description

Eastern terminus of State Highway 20 at Missouri Route 43

SH-20 begins just north of the Arkansas River at SH-18 near Ralston. From there, it heads east through Osage County for 20 miles (32 km) without crossing any other highway. At mile 20.4, it meets State Highway 99 in Hominy. East of Hominy, SH-20 crosses Lake Skiatook before passing through Skiatook and entering Tulsa County. Shortly after entering Tulsa County, SH-20 has a junction with SH-11. Four miles later, it has an interchange with US-75. After running through Collinsville, it turns southward onto the US-169 freeway.

SH-20 splits from US-169 north of Owasso. It then enters Claremore, where it meets SH-88 and SH-66 (old Route 66). It connects to the Claremore toll plaza on I-44/Will Rogers Turnpike. East of Claremore, SH-20 becomes a divided expressway before intersecting US-69 in 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 Spavinaw State Park, before running through the town of Spavinaw, Oklahoma. North of Spavinaw, SH-20 splits off to the east, running through unincorporated Chloeta and serving as the eastern terminus of SH-28. SH-20 overlaps 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 overlaps Arkansas's 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.
