Also part of the loop is 42 miles (68km) of US 71 between Alma and Fayetteville.[3] The US 71 segment allows travelers to go at their own pace through the area. There are many areas and a number of small towns to stop and explore along the US 71 segment as opposed to the bustling interstate segment that bypasses these areas and towns.
U.S. Route 71 in conjunction with Arkansas Highway 23 served the Northwest Arkansas area for many years, but as the area grew the routes became congested. The need for a limited-access highway became apparent, and Interstate 49 was completed through the area by 1999.
