Arkansas Highway 220

Arkansas Highway 220 is a designation for two state highways in west Arkansas. The southern segment of 7.89 mi runs from Oklahoma State Highway 101 near Uniontown to AR 59. A northern segment of 17.04 mi runs from AR 59 north to AR 170 in Devil's Den State Park. The route is not paved within Devil's Den State Park, and was the only Arkansas state highway that remains unpaved until a January 2016 announcement that paving would begin. As of summer 2018, the entire route is now fully paved.
