State Highway 36 (abbreviated SH-36 or OK-36) is a state highway in Oklahoma. It runs for , forming a western loop route from Interstate 44, which it connects to at both ends. It passes through Cotton Co., Tillman Co., and Comanche Co. It currently has no lettered spur routes. State Highway 36 was first added to the highway system around 1926. Route description State Highway 36 begins at Exit 1 on Interstate 44, the first exit north of the Red River on I-44. From this interchange, Highway 36 heads due north to meet US-70. SH-36 turns west to follow US-70, forming a concurrency. The two highways angle northwest to begin paralleling a railroad line. SH-36 and US-70 pass just south of Devol. Approximately thereafter, the two cross the Cotton–Tillman County line. After concurrent with US-70, SH-36 splits away from the U.S. route on the northeast side of Grandfield. As before, SH-36 heads due north from there, crossing over Deep Red Creek and some of its local tributaries. After about alone, the highway forms another concurrency, this time with State Highway 5. The two highways pass to the east of Chattanooga Sky Harbor Airport. After together, SH-5 splits off to the west. SH-36 continues north for around before curving to the east, toward Chattanooga. As Highway 36 crosses into Comanche County, it also enters the town of Chattanooga, which it passes through on 3rd Street. Leaving town, the route continues due east, then curves towards the northeast, crossing Spring Creek. SH-36 next runs through Faxon, continuing northeast; after leaving the town, it bridges West Cache Creek. The highway then resumes a due east course and continues for nearly before reuniting with I-44. At this interchange, the SH-36 designation ends. The roadbed continues east through the interchange; a motorist continuing straight will then be on southbound US-277/US-281 towards Geronimo. History State Highway 36 first appears on the 1927 state highway map, implying that it was added to the system sometime between May 1, 1926, the date of the prior map, and November 1, 1927. The 1927 map shows SH-36 crossing the Red River at a bridge due south of Grandfield. From the bridge, the highway heads north to Grandfield and continues from there along its approximate present-day route. It ended at SH-8 south of Lawton. Between July 1, 1928 and January 1, 1929, the southernmost portion of SH-36 was rerouted. The segment
