Arkansas Highway 85 (AR 85, Ark. 85, and Hwy. 85) is a 9.73miles north–south state highway located entirely within Phillips County in the U.S. state of Arkansas. The highway runs from Highway 44 in Lake View north to U.S. Route 49/Highway 1 (US 49/AR 1) in Walnut Corner. Highway 85 is maintained by the Arkansas State Highway and Transportation Department.
Highway 85 begins at an intersection with Highway 44 at the eastern border of Lake View. Old Town Lake lies to the south of the junction. From here, the route heads north through a rural area along the Lake View border. The road crosses the Johnson Ditch at the northern border of Lake View followed by the Beaver Bayou before entering the community of Oneida. In Oneida, Highway 85 intersects Arkansas Highway 318 at the eastern terminus of a section of the route. Past this intersection, the highway continues north through rural terrain. The route crosses Lick Creek prior to entering Barton. It passes Barton High School before entering Walnut Corner and terminating at a junction with U.S. Route 49 and Arkansas Highway 1.[2]
Highway 85 was designated in 1926 as one of the original state highways. Its route has not changed since its establishment.[3]
