The Appalachian Development Highway System (ADHS) is a series of highway corridors in the Appalachia region of the eastern United States. The routes are designed as local and regional routes for improving economic development in the historically isolated region. It was established as part of the Appalachian Regional Development Act of 1965, and has been repeatedly supplemented by various federal and state legislative and regulatory actions. The system consists of a mixture of state, U.S., and Interstate routes. The routes are formally designated as "corridors" and assigned a letter. Signage of these corridors varies from place to place, but where signed are often done so with a distinctive blue-colored sign.

In Ohio, it follows State Route 32 from the eastern Cincinnati suburbs until a point west of Albany, where it becomes concurrent with U.S. Route 50. After crossing into West Virginia, it follows U.S. Route 50 until the Interstate 79 interchange in Clarksburg.
