State Highway 8, also abbreviated as SH-8 or OK-8, is a highway maintained by the U.S. state of Oklahoma. Because it runs mainly north–south, it has an even number (which is normal for Oklahoma state highways, but opposite from national highways). Highway 8 runs from U.S. Highway 277 in Cyril, Oklahoma to the state line south of Kiowa, Kansas, for a total length of The highway has two lettered spur routes. Highway 8 dates from the creation of the state highway system in 1924. Initially a border-to-border route, it was shortened to its current extent due to encroaching U.S. highways. SH-8 has followed its current route since 1966. Route description The highway begins in Cyril, at US-277 (which at the time is concurrent with State Highway 19), and immediately heads northward. later, the highway passes through Anadarko, sharing a brief overlap with US-62/SH-9. It also becomes concurrent with US-281 here, which it remains with after passing through Anadarko. US-281 and SH-8 continue northward to meet SH-152, which they overlap for . SH-152 splits off to the west at Binger, and US-281/SH-8 go northward through Lookeba to meet SH-37 at its western terminus in Hinton. to the north, the two highways have an interchange with Interstate 40 at its milemarker 101. After this, US-281/SH-8 cross the Canadian River and begin a concurrency with U.S. Highway 270 in Geary. SH-8 splits off by itself after passing through Watonga, to the north. North of Watonga, SH-8 generally runs parallel to SH-51A and, after intersecting SH-51 in Okeene, it runs parallel to SH-58. north of Okeene, SH-58 and SH-8 switch places through a overlap, with SH-8 ending up running to the west through Fairview and SH-58 running to the east to Ringwood. After swapping places with SH-58, Highway 8 continues north, overlapping US-60 for , spending the last also signed concurrently with US-412. north of this, SH-8 has a concurrency with SH-45 southeast of Carmen. Through Cherokee, the Alfalfa County seat, it overlaps U.S. Highway 64 and SH-58. After US-64 splits off to the west, SH-11 joins the concurrency. After , SH-58 splits off to the northeast. SH-11 and SH-8 remain overlapped for seven more miles (11.3 km) before splitting off to the north. SH-8 ends to the north of this at the Kansas state line. After crossing the state line, it becomes K-8, which soon ends at K-2 in Kiowa, Kansas. History SH-8
