In the United States, Corridor D is part of the Appalachian Development Highway System. 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.

The West Virginia portion was constructed during 1967–1977, and the Ohio portion during 2000–2008. ADHS Funding is separate from other Federal Highway funds.
