Route description

OK-20 begins just north of the Arkansas River at OK-18 near Ralston. From there, it heads east through Osage County for twenty miles without crossing any other highway. At mile 20.4, it meets State Highway 99 in Hominy. East of Hominy, OK-20 crosses Lake Skiatook before passing through Skiatook and entering Tulsa County. Shortly after entering Tulsa County, OK-20 has a junction with OK-11. Four miles later, it has an interchange with U.S. 75. After running through Collinsville, it turns southward onto the U.S. 169 freeway.
OK-20 splits from U.S. 169 north of Owasso. It then enters Claremore, where it meets OK-88 and OK-66 (old Route 66). It connects to the Claremore toll plaza on I-44/Will Rogers Turnpike. East of Claremore, OK-20 becomes a divided expressway before intersecting U.S. 69 in Pryor. West of Salina,the highway bridges Lake Hudson. In Salina, OK-20 meets OK-82, which it begins a duplex with.
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, OK-20 splits off to the east, running through unincorporated Chloeta and serving as the eastern terminus of OK-28. SH-20 triplexes with U.S. 59/Oklahoma State Highway 10 through Jay. OK-20 then splits off to the east, running 11 miles to the Arkansas line.
The easternmost miles run north/south along the Oklahoma/Arkansas state line, and along this stretch the highway is duplexed with Arkansas's Highway 43. This is the only place where two state highways from different states are duplexed. In fact, the northernmost mile of OK-20/AR-43 jogs slightly to the west, meaning that in this mile, AR-43 is entirely located in Oklahoma. The highway continues northward into Missouri at the point where the Oklahoma, Arkansas and Missouri borders meet, and thereafter becomes Route 43. This unique feature has led many roadgeeks to mention OK-20/AR-43 on their websites.
