History
The route now known as Highway 7 first appears as a state maintained road in 1924, when the Arkansas General Assembly first created a federal aid system. Two main routes, State Road B-14 and State Road A-5 form a rough trail similar to the present-day Highway 7. Upon creation of the U.S. Route system in 1925, the north and south portions of the highway were replaced by U.S. Route 65 to Harrison and U.S. Route 167, respectively. Arkansas numbered its highways in 1926, and the route became Highway 7 (the north part of A-5 remains as Arkansas Highway 5).
