Oklahoma State Highway 63 - History

History

State Highway 63 was first established on November 6, 1935 as a connection between SH-2 and US-271 in Talihina. On April 1, 1936, the highway was extended east to end at the Arkansas state line. 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. The highway was extended further west on January 29, 1960, bringing it to US-69 in Kiowa. The SH-63 of 1960 had the same basic route as that of the present day. 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.

The current State Highway 1 was designated on February 5, 1968. 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. 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. No further changes have occurred to the highway since.
