Arkansas Highway 15 (AR 15) is a designation for three state highways in Arkansas. One segment of 21.2miles runs from the Louisiana state line north to U.S. Route 82 (US 82) in El Dorado.[2] A second segment of 18.12miles runs from US 79B west of Altheimer north to US 165 in England. A third segment of 16.33miles runs from US 165 in Keo north to Highway 89 in Furlow.
Highway 15 begins at the Louisiana state line as a continuation of Louisiana Highway 161 and runs northeast, cutting through South Arkansas country. The highway serves as a southern terminus for Highway 335 outside El Dorado, Highway 15's lone junction with another state road. Highway 15 next meets the four-lane U.S. Route 82 outside El Dorado, where it terminates.
The route begins at US 79B west of Altheimer and runs north, intersecting Highway 31 in Sherrill near the Sherrill Methodist Episcopal Church and the Tucker School in Tucker before entering Lonoke County, where it terminates at US 165 in England.
The route begins at US 165 in Keo and runs due north across US 70 and I-40 before ending at Highway 89 and Highway 294 in Furlow.[3]
Highway 15 was one of the original 1926 routes designated by the Arkansas Highway Commission. The modern day routes were connected. Highway 15 continued east from El Dorado into Bradley County through Hermitage and Warren.[4] The route continued north into Cleveland County through Pansy and into Jefferson County, where it ran through Pine Bluff and along present-day Highway 31 north to Sherrill, where it meets with today's routing.[5]
The original 1926 routing ended at Highway 36 in England, and no state highway ran to Furlow.[6]
