U.S. Route 412 (abbreviatedUS-412) is aU.S. highway in the south-central portion of the United States, connectingSpringer, New Mexico toColumbia, Tennessee. A 504.11-mile (811.29 km) section of the highway crosses the state ofOklahoma, traversing the state from west to east. Entering the state southwest ofBoise City, US-412 runs the length of theOklahoma Panhandle and serves the northern portion of the state's main body, before leaving the state atWest Siloam Springs. Along the way, the route serves many notable cities and towns, including Boise City,Guymon,Woodward,Enid, and the state's second-largest city,Tulsa.
US-412 has two tolled sections, both of them in Oklahoma—theCimarron Turnpike and theCherokee Turnpike. The tolled portions of the highway are operated by theOklahoma Turnpike Authority (OTA), with the remainder of the route maintained by theOklahoma Department of Transportation (ODOT). In addition to thefreeway-grade turnpikes, a large amount of the highway has been upgraded to four-laneexpressway facilities, although some portions remain two-lane, especially in the Panhandle. Much of US-412's route through Oklahoma eitheroverlaps or is in close proximity to that ofUS-64.
US-412 was extended into Oklahoma in 1988 to encourage recreational travel and the resulting economic benefit to the state. This extension, in which the new designation replaced or overlapped several already existing highways, brought US-412's western terminus to Woodward. In 1993, it was extended west of Oklahoma, bringing it through the Panhandle and into New Mexico.
U.S. Route 412 crosses the New Mexico–Oklahoma state line northeast ofClayton, New Mexico,concurrent withUS-56 andUS-64. The three highways enter the state just north of the extreme southwest corner ofCimarron County, the westernmost tip of theOklahoma Panhandle. The highways head northeast, passing through disconnected parcels of theRita Blanca National Grassland. The first town US-56, US-64, and US-412 encounter in Oklahoma is unincorporatedFelt, which they skirt the northern edge of. The highways then cross theBeaver River before intersectingUS-385, which joins the other three highways in a concurrency as they approachBoise City, the county seat.[2] In Boise City, the highways reach a traffic circle which surrounds theCimarron County Courthouse. At this traffic circle, US-56, US-64, and US-412 all turn east, while US-385 splits away to the north.State Highway 3 (SH-3) enters the circle from the north and leaves from the east, following US-412, whileSH-325 begins at the circle and heads west towardKenton.[3][4] East of town, US-56/US-64/US-412/SH-3 have an interchange withUS-287, which bypasses Boise City to the east. Six miles (9.7 km) northeast of here, US-56 splits away from the other highways; it continues northeast, while US-64/US-412/SH-3 turn onto a due east course. The routes intersectSH-171 eight miles (13 km) east of the split.[5]
Approximately 12 miles (19 km) east of the SH-171 junction, US-64/US-412/SH-3 cross intoTexas County. Seven miles (11 km) east of the county line, at unincorporatedFour Corners,SH-95 joins the concurrency; it splits away after following the other three routes for five miles (8.0 km).[2] The next major highway junction lies 18.1 miles (29.1 km) to the east, whereSH-136 joins with US-64/US-412/SH-3 as the highways turn south towardGuymon. The four highways cross the Beaver River once again before entering that city, Texas County's seat and the largest city in the Panhandle. In Guymon, US-64 splits away to the east, while US-412 and State Highways 3 and 136 continue south, turning back east alongUS-54 to form a short concurrency. A US-412 truck route follows US-64 and US-54 around the east side of the city, reuniting with mainline US-412 where it splits away from SH-136. Just 217 feet (66 m) east of the US-54 junction, SH-136 splits away to the south, leaving US-412 and SH-3 to continue east.[3] Southwest ofOptima Lake, the two highways serve as the southern terminus ofSH-94. East of the highway junction, US-412/SH-3 enterOptima National Wildlife Refuge, where they crossColdwater Creek, one of the lake's tributaries. After leaving the refuge, the routes pass through the town ofHardesty. From Hardesty, the road continues due east, crossing Palo Duro Creek and Chiquita Creek, two tributaries of the Beaver River. The highways then leave Texas County.[2]
The third county US-412 and SH-3 enter isBeaver County, the panhandle's easternmost county. The highways' route across Beaver County is arrow-straight, proceeding due east with only a single curve at the extreme east edge of the county. At the unincorporated location ofBryan's Corner, approximately 7 miles (11 km) east of the county line, the highway intersectsUS-83. Near the county's east–west midpoint, atElmwood, US-412 and SH-3 intersectUS-270 andSH-23. While SH-23 passes through the intersection north to south, eastbound US-270, following southbound SH-23 fromBeaver, joins US-412/SH-3 heading east. The three highways continue on, passing throughSlapout, before curving slightly to the north as they exit both Beaver County and the Oklahoma Panhandle.[2]

Upon entering the main body of Oklahoma, the first county US-270/US-412/SH-3 pass through isHarper County. Here, they intersectUS-283 south ofLaverne; eight miles (13 km) east of US-283, inMay, they intersectSH-46.[5] US-270/US-412/SH-3 only cross the southwest part of Harper County before curving southeast intoEllis County. The routes, however, only clip the northeast corner of the county, traversing only 1.81 miles (2.91 km) of it before passing intoWoodward County.[6]
Shortly after entering Woodward County, US-270/US-412/SH-3 enter the town ofFort Supply. There, the routes junction withUS-183, which joins the other routes as they make their way southeast. Thirteen miles (21 km) southeast of Fort Supply, the four highways enter the city ofWoodward, the largest city within a nine-county area and the commercial hub of northwest Oklahoma.[5][7] On the west edge of town, the four highways serve as the eastern terminus of the western segment ofSH-15, a route made discontinuous by the establishment of US-412 (seehistory). US-270/US-183/US-412/SH-3 proceed east through Woodward. In downtown, they meet withSH-34; here, US-412 leaves the four-way concurrency, as it continues east by itself while the other three highways it has followed since Fort Supply turn south to overlap SH-34 instead. For the first time since its western terminus in New Mexico, where it began concurrent withUS-56, US-412 is the sole highway designation on the road it follows.
As US-412 leaves town, it passes south ofBoiling Springs State Park, running parallel toSH-34C andSH-50B, both of which serve the park. Along this stretch, it crosses the Beaver River for the third and final time, though this time it has since become theNorth Canadian River.SH-50 forms a concurrency with US-412 for 1.3 miles (2.1 km) before splitting off again inMooreland.[3] The highway passes just south ofCurtis as it continues east out of Woodward County.[2]
The next northwestern Oklahoma county that US-412 serves isMajor County. The first intersection with another highway that US-412 comes to is withUS-281 atBouse Junction. East of here, US-412 skirts the northern edge of theGlass Mountains (also known as the Gloss Mountains), turning southeast before returning to a due east course.[2] AtOrienta, the highway begins a concurrency withUS-60 andSH-8; the three highways turn north and together cross theCimarron River. South ofCleo Springs, US-60 and US-412 turn east, while SH-8 splits away to the north. From here, it is a straight shot intoEnid along US-60/US-412; there are no curves along the highway for over 33 miles (53 km). US-60 and US-412 continue to the east, meeting up withSH-58 on the north edge ofRingwood. The two US highways pass throughMeno before coming to the Major–Garfield County line.[3]

Soon after entering Garfield County, US-60/US-412 run throughLahoma. Three miles (4.8 km) east of there, they share a brief concurrency withSH-132.[5] The two highways enter the county seat of Garfield County, the city ofEnid, alongOwen K. Garriott Road, named in honor of the astronaut.[8] In downtown Enid, the routes intersectUS-81; US-60 breaks away from US-412 to turn north along US-81, while US-412 continues east along Garriott Road. On the east side of Enid, US-412 reunites with US-64; the two form a concurrency as Garriott Road becomes an expressway heading east out of town. The next highway junction is an interchange withSH-74; this interchange also serves as the western terminus of the eastern segment of SH-15. From here, US-64/US-412 proceed due east intoNoble County to acloverleaf interchange withInterstate 35 (I-35). US-64 follows I-35 south towardPerry, while US-412 continues straight ahead, where it will form theCimarron Turnpike.[2]

The Cimarron Turnpike, carrying US-412, passes through Noble,Payne, andPawnee Counties. The highway heads east from I-35 to its first interchange, Exit 3, which provides access toUS-77. The first mainline toll plaza is just west of Exit 15, acloverleaf interchange with no straight-line ramps (forcing all traffic getting on or off to pass through the toll plaza) connecting the turnpike toUS-177.[9] East of the US-177 interchange, the highway curves to the south, crossingBlack Bear Creek.[2] US-412 then meets US-64 once again, interchanging with it at Exit 23 east ofMorrison. The turnpike then turns back east, with a spur route (accessible only from the westbound turnpike) branching off to the southwest towardStillwater. The Lone Chimney service plaza, a twenty-four-hour concession area, is located in the median of the turnpike east of the interchange with the spur.[9] South ofPawnee lies an interchange (Exit 37) withSH-18. Just south ofHallett, a second mainline toll plaza sits just west of theSH-99 interchange; again, this interchange is a cloverleaf interchange with only loop ramps. The turnpike's final exit is Exit 60, a partial interchange withSH-48 southeast ofCleveland. The missing movements are provided by US-64, the northern terminus of SH-48, which merges with US-412 as the Cimarron Turnpike ends. The two routes continue east as a freeway.[5]
The US-64/US-412 freeway, known locally as the Keystone Expressway, serves the western outlying areas of theTulsa metropolitan area. Passing south ofWestport, the freeway is routed along a peninsula in extreme southeastern Pawnee County, before crossingKeystone Lake, formed by the impoundedArkansas River, into far southernOsage County. US-64 and US-412 only traverse a short distance in the county, however; after 1.42 miles (2.29 km) the two routes pass intoTulsa County.[10] Just south of the county line, the freeway has an interchange withSH-151, a short connector route that runs across Lake Keystone's dam. At this interchange the Keystone Expressway ends. The Sand Springs Expressway continues from here, throughSand Springs, where it includes an interchange withSH-97 andSH-51, the latter of which joins US-64/US-412 on the freeway. The three routes then continue east intoTulsa proper.[11]
The Sand Springs Expressway comes to an end at the northwest corner of the Inner Disperal Loop (IDL), a ring of freeways surroundingDowntown Tulsa. At astack interchange there, US-64 and SH-51 split away to the south alongI-244; this will be the final intersection US-412 and US-64 will have in Oklahoma. US-412 continues east along I-244. This interchange is also the southern terminus ofL.L. Tisdale Parkway. I-244 and US-412 form the north side of the IDL; at its northeast corner, they interchange withUS-75, the east side of the loop; south of the interchange, US-75 also carries theI-444 designation.[11] I-244/US-412 continue east, with exit ramps to local streets, as well asSH-11 andUS-169. I-244 ends atI-44/SH-66; US-412 forms a concurrency with the latter two routes as they continue east intoRogers County.[5]
Upon entering Rogers County, I-44/US-412/SH-66 parallel the southern boundary of the county, staying just north of the Rogers–Tulsa and, further east, Rogers–Wagoner county lines.[12] In Rogers County, the three highways enter the city ofCatoosa, one of Tulsa's eastern suburbs. In Catoosa, the freeway serves as the southern terminus ofSH-167, which servesthe city's port, and SH-66 splits off towardClaremore. I-44 and US-412 continue east for a short distance before going separate directions; I-44 exits from US-412 and joins theWill Rogers Turnpike. This interchange is also the northern terminus of theCreek Turnpike. US-412 becomes an expressway, and continues east of the interchange, passing throughFair Oaks on its way out of the Tulsa metro. In rural south-central Rogers County, it connects to SH-412P, a state highway spur toPort 33, before crossing theVerdigris River, a component of theMcClellan–Kerr Arkansas River Navigation System.[2] US-412 continues east through unincorporated territory before reachingInola, where it has an interchange withSH-88, 1.39 miles (2.24 km) north of that highway's southern terminus. US-412 then heads eastward out of Rogers County.[12]
After leaving Rogers County, the next county along US-412 isMayes County. South ofChouteau, the route provides access toUS-69 via an interchange. Just west of US-412's crossing of theGrand River, the highway intersects SH-412B, which connects US-412 toSH-69A.[2] After crossing the river, US-412 comes to a fork in the road; one half of the fork is theCherokee Turnpike, which mainline US-412 follows, while the other isUS-412 Alternate, which runs parallel to the turnpike on an old alignment of US-412.[8][13]
The first interchange on the Cherokee Turnpike is withSH-82 inLocust Grove. The turnpike continues east, passing intoDelaware County, to intersect US-412 Alternate again betweenRose andLeach. East of this interchange, a service area lies in the median of the roadway; east of there, the highway passes through the Cherokee Turnpike's only mainline toll plaza. The turnpike's final interchange is withUS-59 andSH-10 inKansas.[9] The Cherokee Turnpike then ends, merging with US-59; at this junction, US-412 Alternate, which was concurrent with US-59, also ends. US-59 and US-412 continue southeast throughFlint, before turning due east toWest Siloam Springs. There, US-59 splits away from US-412, while US-412 remains on an easterly trajectory, crossing the state line intoSiloam Springs, Arkansas.[5]
US-412 initially connectedWalnut Ridge, Arkansas toJackson, Tennessee. Mr. Murphy, deputy director of ODOT, recommended to the Transportation Commission that US-412 be extended into Oklahoma on February 1, 1988. ODOT hoped that establishing US-412 in Oklahoma would generate new recreational traffic, thus benefiting the state economically. The new western terminus was to become the US-183/US-270 junction in Woodward; from there, the highway extended for 288.42 miles (464.17 km) to the east, exiting the state in West Siloam Springs. The Transportation Commission approved the recommendation unanimously.[14]
The US-412 designation was applied to preexisting Oklahoma highways. From Woodward to just east of Enid, US-412 replacedSH-15. From there to the I-35 junction, it was overlaid on US-64; east of I-35, the designation was applied to the Cimarron Turnpike. US-412 continued east from the end of the turnpike along US-64. From there, it was routed through the Tulsa metropolitan freeway system along I-244 and I-44. East of Tulsa, the highway replacedSH-33 to the Arkansas line.[14] The highway designations made redundant by US-412 were removed, effective December 12, 1988.[8]
The first major change to US-412 occurred on November 4, 1991, when US-412 was rerouted onto the newly built Cherokee Turnpike. US-412 Scenic, which was later redesignated US-412 Alternate, was established along the old highway, allowing the highway system to retain a free alternate to the new toll road.[8][13] US-412 was extended west on May 5, 1993; like its initial extension into Oklahoma, this new portion of US-412 followed existing highways: US-56, US-64, US-270, and SH-3.[8][15]
Subsequent changes to US-412 have been more minor. On March 7, 1994, the highway was relocated near Chouteau.[8] Finally, on October 4, 2004, the Transportation Commission approved the realignment of US-60, US-412, and SH-8 at their junction near Orienta.[16] Other than routine maintenance, there have been no further changes to the highway since then.
As of 2013[update], passengers of two-axle vehicles (such as cars and motorcycles) pay a total of $3.00 to travel the entire length of the Cimarron Turnpike and $2.50 to travel the entire length of the Cherokee Turnpike. Tolls vary based on the entrance and exit used. Both turnpikes accept OTA'sPikepass transponder system as an alternative to cash payment. Pikepass customers receive discounted toll rates; the Pikepass rate for the full length of the Cimarron is $2.85, and the discounted rate for the Cherokee is $2.40.[17]
Toll revenues from the two turnpikes US-412 uses are not necessarily used to maintain those highways. Under a practice known ascross-pledging, all OTA toll revenue is pledged against the sum of OTA's indebtedness, including bonds financing the state's other turnpikes.[18]

On May 20, 2021,SenatorJim Inhofe,Republican of Oklahoma, introduced legislation to designate the portion of US-412 between I-35 in Noble County andI-49 inSpringdale, Arkansas as future Interstate 42. (I-42)[19][20] The bill, titled the "Future Interstate in Oklahoma and Arkansas Act" (S. 1766), was cosponsored by senatorsJohn Boozman andTom Cotton, both Republicans of Arkansas. The senators' stated reasons for seeking an Interstate designation along the US-412 included encouraging economic development, expanding opportunities for employment in the region, making travel safer and shipping easier, attracting new businesses, and better connecting rural and urban communities. Other supporters of the measure include themayor of Tulsa,G. T. Bynum, and the heads of both ODOT and theArkansas Department of Transportation (ArDOT).[21] The language of the bill was later included in theInfrastructure Investment and Jobs Act (H.R. 3684). Interstate 42 (I-42) was the proposed designation but was withdrawn.[22] ArDOT and ODOT later resubmitted the application to the Spring 2024 meeting; AASHTO approved the route as Interstate 42, conditional on it being upgraded toInterstate standards.[23]

US-412 anchors three state highway spur routes in Oklahoma. These three routes all bear the number "412" with a letter suffix, on an Oklahoma state highway shield.
| Location | Oaks, Oklahoma |
|---|---|
| Length | 2.98 mi[24] (4.80 km) |
| Existed | ca. 1957–present |
State Highway 412A is the only US-412 spur route to not directly connect to mainline US-412. SH-412A has a total length of 2.98 miles (4.80 km).[24]
SH-412A begins at theCherokee–Delaware county line in the town ofOaks. The route proceeds north through town. After leaving Oaks, the highway enters unincorporated territory before ending at US-412 Alternate at the unincorporated location ofTwin Oaks.[24]
SH-412A existed prior to the extension of US-412 in Oklahoma. As the adjacent section of highway was part of SH-33 prior to becoming US-412, what would become SH-412A was originally designated as SH-33C. SH-33C was first shown on the Oklahoma state highway map in 1958.[25] At the time of the highway's designation, it was a gravel highway; by 1959, however, it had been paved.[26] The first revision of the state highway map to reflect the renumbering of SH-33 to US-412 was the 1989 edition; this was also the first to show SH-33C redesignated as SH-412A.[27]
| Location | Mayes County, Oklahoma |
|---|---|
| Length | 5.33 mi[28] (8.58 km) |
| Existed | ca. 1986–present |
State Highway 412B is a spur route of US-412 lying entirely within Mayes County. It is 5.33 miles (8.58 km) long.[28]
SH-412B begins at US-412 just west of the Grand River bridge and the western terminus of the Cherokee Turnpike. From there, the highway follows a winding path to the north, passing east of Chouteau, before ending atSH-69A betweenMidAmerica Industrial Park to the west andSportsmen Acres to the east.[2]
The highway that is currently SH-412B was first shown on the official state map in 1987 as SH-33G, connecting to SH-33 at its southern terminus.[29] By 1989, the first edition of the map to show US-412 in Oklahoma, SH-33G had been renumbered to SH-412B.[27]
| Location | Rogers County, Oklahoma |
|---|---|
| Length | 1.26 mi[12] (2.03 km) |
