SH-108 was added to the state highway system on July 11, 1955. At this time, the highway had the same extent as it does today; the only changes made to the highway over the years were slight modifications to its alignment due to the straightening of connecting highways.

Route description

SH-108 begins in Payne County approximately halfway between Perkins and Cushing at SH-33. From here, the highway runs north on Ripley Road. About two miles (3.2 km) into its journey,[3] the road passes through the town of Ripley (pop. 444).[4] North of Ripley, it crosses the Cimarron River. Seven miles (11 km) later, the highway intersects SH-51, and SH-108 turns west along it, forming a one-mile (1.6 km) concurrency.[4] SH-108 then continues north on Rose Road.[3]

Approximately eight miles (13 km) north of SH-51, SH-108 enters Glencoe (pop. 583).[4] The highway then crosses the Cimarron Turnpike on a grade separation with no interchange. The highway shifts to the east about one mile (1.6 km) north of Glencoe.[3] Upon exiting Payne County, the highway straddles the Noble–Pawnee County line all the way to its terminus at US-64 in the unincorporated settlement of Lela.[3]

As of 2012, the highest average annual daily traffic (AADT) count along SH-108 was 5,900, measured along the concurrency with SH-51. The highest traffic volume on SH-108 alone was an AADT of 1,900, measured north of SH-51. The lowest AADT measured was 1,500, which occurred both in Glencoe and south of Ripley.[5] No part of SH-108 has been designated as part of the National Highway System.[6]

History

SH-108 was first designated on July 11, 1955.[2] The highway was mostly gravel at that time; only the portions from the southern terminus to Ripley and the concurrency with SH-51 were paved.[7] In 1960, the section of SH-108 between SH-51 and Glencoe was paved.[8] In 1963, the paved segment extended north of Glencoe, to the highway's northern terminus.[9]

The first change to the highway's alignment occurred on November 1, 1966, when SH-51 was straightened between Stillwater and Yale; SH-108 was realigned to continue to concur with SH-51.[2] Around the same time, the remainder of SH-108 was paved.[lower-alpha 1] The final change to SH-108 was made on June 4, 1974, when a straightening of SH-33 resulted in a slight extension of SH-108 to continue to meet the new highway. No changes have been made since.[2]
