Also in 1986, US 74 was extended west, from Asheville to Chattanooga, Tennessee. The routing extension starts at its former western terminus with US 70, going northerly, in concurrency with US 70, to I-240, where it overlaps briefly before joining US 19/US 23. From Asheville, in concurrency with US 19/US 23, it goes through Canton, Lake Junaluska and Waynesville. Near Dillsboro it switches US 23 for US 441 and continues till it splits north within the Qualla Boundary. West of Bryson City, it overlaps with NC 28. In Topton, it joins with US 129 and continues southwesterly till at Murphy, where it joins with US 64 and separates from US 19/US 129. Heading west, in concurrency with US 64, it enters Tennessee; traversing through Ducktown, it reaches Cleveland, where it then follows the US 64 Bypass to I-75. Continuing southeasterly, as a hidden concurrency with I-75, it connects with Chattanooga, ending at its new terminus at I-24.
