State Highway 45 (SH-45 orOK-45) is astate highway inOklahoma. It runs 64.7 miles (104.1 km) west-to-east throughWoods,Alfalfa andGarfield counties.[2]
SH-45 begins at theUS-281/SH-14 junction inWaynoka. The first 12 miles (19 km) of SH-45 heading east out of Waynoka isconcurrent with US-281. US-281 then splits off to the north. SH-45 continues east for 12 miles (19 km) toCarmen.[3]
Two miles (3.2 km) east of Carmen,SH-34 joins SH-8 for a 3 miles (4.8 km) concurrency to the south, where SH-43 resumes its eastward travel.SH-58 joins SH-43 for a one-mile (1.6 km) concurrency just south of the town ofHelena, and atGoltry, SH-45 jogs south a few miles before turning back to the east and heading for a brief concurrency withSH-132 atCarrier. Continuing to the east, SH-45 travels eight more miles (12.9 km) from Carrier, before reaching its terminus at US-60/64/81 at the north edge ofEnid.[3]
SH-45 was first added to the state highway system between May 1926 and November 1927. The original routing of the highway was from Waynoka to SH-8 in Carmen.[1]
Before 1963, the section of present-day SH-45 between SH-58 and SH-132 was part of the original SH-38.[4] In 1963, all of this SH-38 west of Carrier was renumbered to SH-45 (a north–south section of SH-38 that connected Carrier to US-60 became part of a SH-132 extension). The same year, SH-45 was extended westward to Waynoka.[5] In either 1971 or 1972, the highway was extended eastward to its present terminus on the northern outskirts of Enid.[6] No major changes have occurred since.
