was one of the original thirty-one state highways created on 1924-08-24. When it was created, it was a border-to-border highway, stretching from Texas to Kansas. It began at the Red River near Burkburnett, Texas. It then passed through Randlett and had a short concurrency with SH-5 west of Walters. The highway then ran through Lawton—concurring with the original SH-29—en route to Anadarko via Apache. In Anadarko, SH-8 linked up with the present highway. The remainder of the route was mostly the same as it is today. In November 1926, AASHTO officially approved the United States Numbered Highways system. The Oklahoma Transportation Commission applied the national highways to Oklahoma's state highway system on 1926-11-26. Three U.S. highways were assigned to portions of what was then SH-8: U.S. Highway 64 was added to a segment of highway south of Cherokee, U.S. Highway 66 was added between Bridgeport and Geary, and U.S. Highway 70 was added from the Texas state line to Randlett. US-66 and 64 merely ran concurrently with SH-8. However, US-70 completely replaced the state highway, which was truncated so that its southern terminus was at US-70 in Randlett. By 1936, several U.S. highways had been added to the system that took over parts of State Highway 8's route. US-62, added in 1930, took over the Lawton–Anadarko portion of the road. US-277 took over much of the remaining route between Randlett and Lawton. In addition, a US-70N had been created that overlaid US-277 between Randlett and the split with SH-5 west of Walters. These changes to the U.S. route system precipitated the truncation of SH-8 in 1936. On 1936-03-13, the section of the route between Anadarko and the state line was dropped. However, a new road between Anadarko and Cyril had been built; this became part of SH-8 and set the highway's southern terminus at its present location. By the end of 1937, however, the highway's southern terminus had changed once again. On 1937-10-19, SH-8 had been truncated to Anadarko. However, on 1938-10-18, the route was extended back to the former southern terminus at Randlett; this change did not appear on the state map until the April 1941 edition. On 1941-04-14, the route was realigned to run through Cyril once again. On 1955-09-12, SH-8 underwent a small realignment. Previously, the highway went due north from Carmen, then turned due east, running through Lambert before connecting to US-64 south of Cherokee. As
