State Highway 6, abbreviatedSH-6 orOK-6, is astate highway inOklahoma. It runs in a 121.8 miles (196.0 km) crescent through the southwestern part of the state, running from the Texas state line north ofQuanah, Texas, toSH-152 in the town ofSweetwater. There are no letter-suffixed spur branching from SH-6.
SH-6 was added to the state highway system in 1954. The highway was later extended from its original extent; westward from Elk City in 1957 and southward to Texas in 1975.
After crossing theRed River,State Highway 6 leavesTexas, becomes SH-6 and continues headed northeast, passing through the smallJackson County towns ofEldorado andOlustee. Highway 6 meetsUS-62 five miles (8 km) west of Altus.[2] SH-6 makes a right turn at this point tooverlap US-62 intoAltus.
In Altus, SH-6 takes a turn to the north to overlapUS-283. North ofBlair, US-283 heads due north while SH-6 turns toward the northwest. SH-6 crosses US-283 once more before the state highway continues to the north towardGranite, where it meetsSH-9.
North of Granite, SH-6 runs along theBeckham–Washita county line until sharing a 4-mile (6.4 km) concurrency withSH-55, moving into Beckham County.[2] After splitting away from SH-55, it meetsSH-152 for the first time (it will meet SH-152 at its northern end.)
SH-6 continues north to have an interchange withInterstate 40 inElk City. It overlapsBusiness Loop I-40 for four miles (6.4 km) on the north side of the city.[2] At this point the north–south highway curves to the west. It crosses US-283 (again), and then ends at SH-152 in Sweetwater.
The original State Highway 6 extended from the Texas state line nearColbert to the Kansas state line north ofVinita.[3] When theUnited States Numbered Highways system was established in 1926, the vast majority of the highway was overlapped byUS-75 andUS-73.[4] (Later, this corridor would form the majority ofUS-69 in Oklahoma). As a result, the original SH-6 designation was decommissioned soon after the establishment of the U.S. highway system.[citation needed]
The SH-6 designation remained unused until August 21, 1954, when it was assigned to a highway beginning at US-283 east ofMangum, extending north through Granite and Retrop, and ending at US-66 in Elk City.[5][6] The highway was extended west alongSH-73 to its current northern terminus on January 21, 1957.[5]
SH-6 was extended to the south on July 7, 1975, bringing it to Altus by way of a concurrency with US-283, where it joined US-62 in another concurrency, headed west. West of Altus, the route split off and headed southwest to the Texas state line. In addition to the U.S. routes, SH-6 was concurrent with SH-44 between that route's current southern terminus and Eldorado, where it ended; thereafter, SH-6 followed SH-34 to the Red River. To remove the redundant designations, both SH-34 and SH-44 were truncated to their current southern terminus on January 5, 1987.[5][7][8]
SH-6 was realigned twice in 2004 to allow SH-6 a straighter route in situations where it was concurrent with another highway. The first such section removed a portion of the US-283 concurrency between Blair and Granite; the second realignment took place on the SH-55 concurrency north of Retrop. Both of these changes were applied to the highway on February 2, 2004.[5] No further changes to the highway's route have taken place since then.
