State Highway 47 (SH-47 or OK-47) is a state highway in Oklahoma. It runs 94.6 miles (152.2 km) west-to-east in Roger Mills, Dewey and Custer counties.^[1]

The current SH-47 was first established in late 1936. Over time it was expanded, reaching its current extent in 1945. A lettered spur route, SH-47A, was added in 1965.

Route description

State Highway 47 begins at the Texas state line, where FM 2124 becomes SH-47 upon entering Oklahoma, in the Black Kettle National Grassland. Four miles (6.4 km) later, SH-30 joins the highway for a three-mile (5 km) concurrency just south of Reydon.^[3] Just outside the community of Rankin, SH-30 turns to the south, and SH-47 continues off to the east.

A few miles west of Cheyenne, SH-47A branches off in a loop to the north, rejoining Highway 47 in a couple of miles. South of Cheyenne, SH-47 joins US-283 for a concurrency to the north. SH-33 also joins in on the concurrency, with a signed direction opposite that of SH-47 (a wrong-way concurrency). SH-47 and US-283/SH-33 parts ways at Roll, where SH-47 resumes its travel to the east.

From Roll, the highway travels 21 miles (34 km) to a junction with SH-34 just south of Leedey.^[3] SH-47 continues east for 22 miles (35 km) until it reaches a junction with US-183.^[3] There, it turns to the south for a five-mile (8 km) concurrency.^[3] After leaving US-183, SH-47 travels another 13 miles (21 km) to the east to its terminus at SH-33 in Thomas.^[3]

History

The current incarnation of State Highway 47 was first commissioned on November 12, 1936.^[2] Originally, the highway began at SH-34 south of Leedey and proceeded east to end at SH-14 (present-day US-183) south of Putnam.^[4] However, the road was removed from the state highway system just over a year later, on the last day of 1937. It was brought back with the same extent on June 19, 1939.^[2]

Throughout the early 1940s, SH-47 underwent a period of expansion. The first extension of the highway came on June 20, 1940, when it was extended west to end at US-283 in Roll.^[2][5] SH-47 was extended east to Thomas via US-183 on May 31, 1944.^[2] The final extension occurred on October 1, 1945, when the highway was extended south down US-283 to Cheyenne, then west to the Texas state line.^[2]

SH-33 and SH-47 swapped places west of US-283 on July 9, 1956; SH-47 proceeded due west of Roll to the Texas state line, while SH-33 passed through Cheyenne and turned toward the west south of there.^[2] This gave both highways straighter courses and resolved the wrong-way concurrency. However, the change was rescinded on August 13, 1956.^[2]

Two minor realignments were done to SH-47 in the 1960s. The first, on April 3, 1961, relocated the highway west of Aledo, while the other one, on May 5, 1964, adjusted it between Roll and Angora. SH-47 has undergone no changes since.^[2]

Spurs

Two highways have served as branch routes during SH-47's history. Both of these bore the SH-47A designation.

Historic

Historically, SH-47A was a spur serving the central business district of Reydon. The highway was commissioned on a temporary basis on February 8, 1950. Its alignment was adjusted, and the highway received a permanent commission, on January 8, 1951. The highway was turned back over to the town on December 6, 1954.^[2]

Current

The current SH-47A is a 2.15-mile (3.46 km) loop route that connects to SH-47 at both ends west of Cheyenne.^[6] The highway is entirely located within Roger Mills County and the Black Kettle National Grassland. It provides access to the Washita Battlefield National Historic Site.

SH-47A was commissioned on September 7, 1965.^[2]
