All are minor state highways established to provide system connectivity and are maintained by the Arkansas Department of Transportation (ArDOT).

ArDOT maintains all three segments of AR 156 as part of the state highway system.

Continuing on Highway 170 east gives access to Interstate 49 (I-49) and the Boston Mountains Scenic Loop.

The highway continues north before a junction with Pump Station Road, where state maintenance ends.

From the eastern terminus, the road continues due north under local maintenance to Highway 16.
