History
Between Bentonville and Gravette, Highway 72 follows a former alignment of U.S. Route 71. In the late 1990s, Highway 72 was rerouted away from downtown Bentonville along US 71B, Highway 102, and Highway 112.
Arkansas Highway 72 Spur (AR 72B) is a former spur route in Bentonville. Its southern terminus was at an intersection with US 71 with a northern terminus at an intersection with Highway 72 in Bentonville. Running a total distance of 1-mile (1.6 km), it was an older alignment of US 71 and at one time was part of US 71B.
