As part of the agreement, ARDOT would build and pay for the widening projects, with Fayetteville accepting the road under city maintenance and control after the widening was complete.

[8] Highway 112 is also designated as part of the Arkansas Trail of Tears northern route.

However, the route quickly became congested itself due to the growing population of Bentonville and the desire to find a quicker route to reach the Northwest Arkansas National Airport.

[10] As a result, the Arkansas Department of Transportation (ArDOT) has made plans to widen a 12 mi (19 km) stretch of the route between US 412 in Tontitown to its northern terminus at Highway 12 in Bentonville.

[11] In late-September 2023, the Federal Highway Administration (FHA) approved ArDOT's request for a Finding of No Significant Impact (FONSI), allowing them to begin right-of-way acquisition for the widening of the roadway.
