Oklahoma State Highway 34

For much of its extent, State Highway 34 passes through rural areas, running through the plains of western Oklahoma. The highway begins at SH-6 six miles (10 km) northeast of Eldorado.[3] Heading north from there, it intersects U.S. Route 62 (US-62) just east of Duke. The highway continues north into Greer County to its county seat of Mangum, where SH-34 joins US-283. Two miles (3 km) north of Mangum, SH-9 joins for a four-mile (6 km) concurrency with SH-34 and US-283. Thereafter, SH-9 splits off to the east.[3]

Nine miles (14 km) north of Mangum, SH-34B branches off to the west, connecting to the town of Brinkman, and four miles (6 km) later, SH-34A branches off to the west to the town of Willow.[3] US-283 splits off to the northwest two miles (3 km) after that, and SH-34 continues north, crossing into Beckham County. SH-34 then bridges over the North Fork of the Red River. In Carter, the highway serves as the western terminus of SH-55. Five miles (8 km) north of Carter, SH-34 crosses SH-152.[3]

SH-34 continues on to an interchange with Interstate 40 (I-40) west of Elk City. Here, the highway begins a concurrency with eastbound I-40. SH-34 accesses I-40 from exit 32, a partial diamond interchange, with no access to or from I-40 eastbound; the missing movements must be completed via another partial interchange further to the east, also numbered as exit 32, which serves Business I-40 (I-40 BUS). SH-34 follows I-40 to the east for 6 miles (9.7 km).[3] While concurrent with I-40, SH-34 has an interchange with SH-6, its northernmost junction with the latter highway. SH-34 exits the interstate from the left at exit 41 on the east side of Elk City, turning back to the north and intersecting I-40 BUS. The highway continues north out of Elk City, exiting Beckham County.[1]

After leaving Beckham County, SH-34 enters Roger Mills County. SH-73's western terminus is at SH-34 at nine miles (14 km) north of Elk City.[3] North of this junction, SH-34 lies along the Roger Mills–Custer county line, which it continues to follow as it passes through the east side of Hammon, where it meets State Highway 33. North of town, the route crosses over the Washita River, and shortly thereafter turns northeast to fully enter Custer County. Northwest of Moorewood, the highway crosses into Dewey County.[4]

In Dewey County, SH-34 crosses SH-47, two miles (3 km) south of Leedey, and crosses the Canadian River near the unincorporated settlement of Trail. The highway then passes through Camargo. Just east of Vici, SH-34 joins US-60 and SH-51 for a one-mile (1.6 km) concurrency, then SH-34 heads north again at Vici.[3] The highway passes through Sharon north of Vici, then joins US-183/US-270/SH-3 four miles (6 km) southeast of Woodward. At Woodward, SH-34 again sets off to the north alone, and right after crossing the North Canadian River, SH-34C branches to the east about two miles (3 km) north of Woodward, connecting to Boiling Springs State Park.[3]

SH-34 joins US-64 in far eastern Harper County for a four-mile (6 km) concurrency to the east, crossing the Cimarron River 17 miles (27 km) east of Buffalo. The highway then turns back to the north, where it is 10 miles (20 km) to its terminus at the Kansas state line.[3]

State Highway 34 was first designated on June 15, 1931.[2] At that time, the highway began at the free bridge over the Red River north of Quanah, Texas, and followed what is today SH-6 to the point that is now SH-34's southern terminus. There, it turned north, following its current alignment. Its 1931 alignment did not differ significantly from that of the present day (although it followed US-66 through Elk City prior to the establishment of I-40) until it got to Woodward. Rather than continue north out of town, the SH-34 of that day instead turned west, then north, passing through Fort Supply and crossing into Harper County just north of that town. It then began a concurrency with US-60 in Buffalo, turning east and connecting with its final segment, bringing it to the Kansas state line. Thus, SH-34 started life as a border-to-border highway.[5]

SH-34 was rerouted north of Buffalo on January 30, 1934.[2] The new alignment continued due north out of Buffalo to the Kansas state line along a new road. The old portion of SH-34 between US-64 and the Kansas state line became part of SH-50.[6]

The next major change to SH-34 occurred in 1954. On November 1 of that year, the highway was realigned to follow a new road extending north of Woodward, intersecting US-64 east of Buffalo, and following existing highways north to the state line.[2] This would put SH-34 on its present-day route north of Woodward.[7] SH-50 would remain concurrent with SH-34 north of US-64 until November 9, 1964.[8]

The next major change to SH-34 would be brought about by the establishment of the southern part of State Highway 6. The new highway was introduced on July 7, 1975.[9] SH-34 remained in place; the two highways were concurrent from northwest of Eldorado to the Red River bridge, where they both ended. On January 5, 1987, the redundant section of SH-34 was removed, truncating it to its current southern terminus.[2][9]

The final modification to SH-34 occurred just under a month later, on February 2, 1987, when SH-34 was realigned in Elk City to follow I-40 instead of the old alignment of the now-dead US-66, which had become a business loop of I-40. No further changes have taken place since then.[2]
