Highway 18 was created during the 1926 Arkansas state highway numbering from Diaz to Barfield similar to the present-day alignment.[5] The designation was shifted onto Nettleton Cut-Off Road in Jonesboro on March 9, 1955.[6] The highway was rerouted between Leachville and Manilla on July 10, 1957, with Highway 18 taking over the former alignment of Highway 18 Spur.[7] It was extended to Barfield Landing on April 24, 1963 as part of a major expansion of the state highway system.[8] The western terminus was extended west to Highway 69 in Jacksonport on November 23, 1966.[9]
