State highway in Arkansas, United States
Highway 4 (AR 4, Ark. 4, and Hwy. 4) is a designation for two state highways in Arkansas. The western segment of 2.99 miles (4.81 km) runs from SH-4 at the Oklahoma state line and terminates in Cove.[2] An eastern segment of 22.49 miles (36.19 km) begins at U.S. Route 278 (US 278) in McGehee and heads east to Arkansas City then north to Highway 1 before terminating.[3] The two routes were formerly connected until a portion of approximately 230 miles (370 km) was redesignated US 278 in 1998.[citation needed] The eastern segment is part of the Great River Road.
