Oklahoma State Highway 89

State Highway 89 begins at the Taovayas Indian Bridge[2] on the Illinois Bend of the Red River, continuing Farm to Market Road 677 from Texas. One mile (1.6 km) north of the river, it intersects SH-32 at Courtney.[1] SH-89 overlaps SH-32 for 6.1 miles (9.8 km),[1] initially headed due west, but curving around to the northwest and eventually the north, crossing into Jefferson County and passing through unincorporated Petersburg. SH-32 then angles off to the northwest while SH-89 continues on a due north course.

After splitting off to the north, SH-89 travels through eastern Jefferson County for 13.4 miles (21.6 km),[1] generally paralleling the county line.[3] The highway continues along a rough northerly heading, though it briefly heads northwest at times. SH-89 runs to the east of the town of Cornish, and then intersects US-70 as it enters Ringling. After passing through the town, it curves northwest. SH-89 then turns back to a due north course, which it will maintain for the rest of its existence. The highway comes to an end 9.8 miles (15.8 km) north of Ringling at SH-53 east of Loco.

State Highway 89 was first added to the Oklahoma state highway system on July 26, 1944.[2] The original extent of the highway was from the current northern junction with SH-32 to US-70 in Ringling.[4] These remained the route's termini until January 21, 1957, when it was extended north through Ringling to SH-53, setting its northern terminus at its present location. Minor realignments would take place during the next two years, after which the highway would remain the same for three decades.[2]

On September 6, 1994, the highway was extended south. SH-89 now overlapped SH-32 to Courtney, where it split away towards its new southern terminus at the Texas state line. The highway has undergone no further changes since this extension.[2]
