State highway in Arkansas, United States
Highway 28 (AR 28, Ark. 28, and Hwy. 28) is designation for three east–west state highways in Western Arkansas. Two segments together running from the Oklahoma state line to Ola (with a gap along US Highway 71 around Waldron) have been established since the original 1926 Arkansas state highway numbering, with the third segment designated in 1963. All three highways are rural, two-lane roads with relatively low traffic serving a sparsely populated and forested part of Arkansas. The highways are maintained by the Arkansas Department of Transportation (ARDOT).
