For the majority of its routing through Arkansas, I-40 follows the historic alignment of two separate U.S. Highways. From Oklahoma to Little Rock, I-40 generally follows U.S. Highway 64 through the Ozark Mountains. East of Little Rock, the route generally follows the routing of US 70 until the Tennessee state line.
