State Highway 63 (abbreviatedSH-63) is a 96.7 miles (155.6 km)[2]state highway in southeasternOklahoma. It runs fromU.S. Highway 69 inKiowa to the Arkansas state line. SH-1 forms aconcurrency with SH-63 for 37.8 miles (60.8 km), nearly 40 percent of the highway's length.[2] SH-63 has one spur route, designated as SH-63A.
SH-63 was added to the state highway system on November 6, 1935, as a short link highway between Talihina and SH-2. The highway was gradually extended to its present length between then and 1960. When the current incarnation of SH-1 was established, the middle of SH-63 was turned over to the new highway, leaving SH-63 in two separate parts. The two sections were connected via a concurrency in the early 1980s.
SH-63 heads northeast from Kiowa, passing throughPittsburg and crossing under theIndian Nation Turnpike nearBlanco. InHaileyville, it meetsUS-270/SH-1 and begins aconcurrency with them. After passing throughHartshorne, US-270 splits off. Seven miles (11 km) later, the highways pass through unincorporatedHiggins, then continues east for 9 miles (14 km), where they meetsState Highway 2 and the two highways concur with it.[3]
The SH-1/2/63 concurrency heads south for six miles (9.7 km).[3] West ofBuffalo Valley, SH-2 splits off to the south as SH-1/63 head east. InTalihina, the highways meetUS-271, which SH-1 joins. SH-63 heads east alone, passing throughWhitesboro andMuse. InBig Cedar, it crossesU.S. Highway 259. It then entersOuachita National Forest and ends at the state line. Arkansas Highway 8 continues on toMena.
State Highway 63 was first established on November 6, 1935, as a connection between SH-2 and US-271 in Talihina.[1] On April 1, 1936, the highway was extended east to end at the Arkansas state line.[1][4] This remained the highway's extent for the remainder of the 1930s and the 1940s.
The highway was extended west for the first time on August 4, 1952, when SH-63's western terminus was set at US-270 near Hartshorne.[1] The highway was extended further west on January 29, 1960, bringing it to US-69 in Kiowa.[1] The SH-63 of 1960 had the same basic route as that of the present day.[5] Minor realignments to the highway occurred on September 6, 1962, northwest of the northern SH-2 junction, and through Haileyville and Hartshorne on August 3, 1964.[1]
The current State Highway 1 was designated on February 5, 1968.[1] The portion of highway between Haileyville and Talihina was made solely part of SH-1. This left SH-63 in two discontinuous sections, one between Kiowa and Haileyville and one from Talihina to the Arkansas line.[6] This situation would persist for fifteen years. On July 7, 1983, SH-63 was restored between the two segments, forming the SH-1/63 concurrency.[1] No further changes have occurred to the highway since.

SH-63 has one lettered spur,SH-63A. SH-63A begins at SH-1/63 two miles (3 km) west of Talihina. It heads north for1⁄4-mile (0.40 km) before forking into two separate highways. The west fork goes to the Choctaw Nation hospital, while the east fork goes to theOklahoma Veterans Center.[7] The west fork is exactly 1.00 mile (1.61 km) long, and the southern and eastern forks together are 1.40 miles (2.25 km), for a total combined length of 2.40 miles (3.86 km).[8]
