Corridor Q is a highway in the U.S. states of Kentucky, Virginia, and West Virginia. It is part of the Appalachian Development Highway System and U.S. Route 460. Corridor Q runs from Corridor B (US 23/US 119) near Pikeville, Kentucky easterly to Interstate 81 in Christiansburg, Virginia.
Corridor Q does not meet any ADHS Corridors other than B, but it meets the planned Coalfields Expressway (U.S. Route 121) near Grundy, Virginia, the King Coal Highway (U.S. Route 52) in Bluefield, West Virginia, and Interstate 77 just to the east near Princeton. At its west end, traffic can continue northwesterly along Corridor B, Corridor R, Corridor I, and Interstate 64 to reach Lexington, Kentucky. The part of Corridor Q east of Bluefield is part of the I-73/74 North-South Corridor.
