Arkansas Highway 45 (AR 45) is a designation for three state highways in Northwest Arkansas. One segment of 26.97 miles (43.40 km) runs from Highway 96 north to Interstate 540 (I-540) in Fort Smith. A second segment of 10.64 miles (17.12 km) runs from Highway 59 north of Dutch Mills north to U.S. Route 62 (US 62) east of Lincoln. A third segment of 25.42 miles (40.91 km) runs from College Avenue in Fayetteville north to Highway 12 west of Clifty. These routes were formerly connected until a portion of approximately 50 miles (80 km) was redesignated Highway 59 and many United States highways were rerouted through Fayetteville.
