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. 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. 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. ==Junction list==
