Corridor J is a highway in the U.S. states of Tennessee and Kentucky. It is part of the Appalachian Development Highway System, running from the end of Interstate 124 in Chattanooga, Tennessee north to Interstate 75 in London, Kentucky.[1]
Corridor J uses U.S. Highway 27 from Chattanooga north to Soddy-Daisy. There it turns northwest on State Route 111, eventually curving to the north via Dunlap, Sparta, and Cookeville to Livingston. Then it turns northwest on State Route 52 to Celina and northeast on State Route 53 to Kentucky.
Upon crossing into Kentucky, Corridor J becomes Kentucky Route 61, heading north to Burkesville. There it turns east on Kentucky Route 90, which it follows to Burnside. Corridor J turns north on U.S. Highway 27 at Burnside, quickly turning northeast on Kentucky Route 914 to bypass downtown Somerset[citation needed] and then east on Kentucky Route 80 to London.
The proposed Interstate 175 would follow Corridor J.
Until late 2005, Corridor J was to turn west just north of Cookeville along the planned State Route 451 to State Route 56 north of Baxter and then use SR 56 and SR 53 via Gainesboro.[2][3]
