Corridor B is a highway in the U.S. states of North Carolina, Tennessee, Virginia, Kentucky, and Ohio. It is part of the Appalachian Development Highway System, and generally follows U.S. Route 23 from Interstate 26 and Interstate 40 near Asheville, North Carolina north to Corridor C north of Portsmouth, Ohio.[1]
Corridor B uses Interstate 240 from its south end into downtown Asheville, where it uses US 23 (current and future Interstate 26) to Kingsport, Tennessee. The US 23 freeway ends at the Tennessee/Virginia state line, but US 23 is a four-lane divided highway all the way through Virginia and into northeastern Kentucky.[2]
At Grays Branch, Kentucky, Corridor B leaves US 23 to turn east on Kentucky Route 10 over the two-lane Jesse Stuart Memorial Bridge into Ohio. The short State Route 253 connects the bridge to U.S. Route 52, a freeway that takes Corridor B north to Sciotoville. US 52 continues west to Portsmouth, but the proposed alignment of Corridor B continues north and northwest along the planned Portsmouth Bypass to US 23 near Lucasville. The part of Corridor B north of SR 253 is also part of the I-73/74 North-South Corridor.[3]
Corridor B-1 runs from Kentucky Route 10 to the north end of the Portsmouth Bypass. In Kentucky, it follows US 23 and U.S. Highway 23 Truck; after crossing the two-lane Carl Perkins Bridge into Ohio, it uses current and planned State Route 852 - a western bypass of Portsmouth - and US 23. Corridors B and B-1 both end near Lucasville, where Corridor C continues north along US 23 to Columbus.[3]
