On the east side of Knoxville it becomes concurrent with U.S. 25W and U.S. 11E and carries the name Asheville Highway from Knoxville to the community of Trentville in eastern Knox County. At Trentville, US 11E separates from the concurrency. U.S. 25W remains overlapped with U.S. 70 to Newport, where U.S. 70 is joined by U.S. 25E, which becomes US 25. U.S. 25 and U.S. 70 remain concurrent into North Carolina. North Carolina US 70 enters North Carolina as a two-lane road in concurrency with US 25. Going southeast, it widens to four-lane near Marshall, merging farther down with I-26/US 19/US 23 going into Asheville. In the downtown area, it breaks from the U.S. 19/23 freeway onto city streets and through Beaucatcher Tunnel as it goes east; paralleling north of I-40, going through the cities Marion, Morganton, Hickory, Conover and Statesville. From there, it goes southeast to Salisbury, where it starts to parallel I-85 north through Lexington, Thomasville, High Point and Greensboro, in concurrency with I-85 Bus/US 29. US 70 passes through Greensboro in concurrency with Interstate 40, Interstate 85 Business, then US Routes 29 and 220 briefly, then heads east through the Wendover Avenue expressway, which takes the route out of town towards Burlington. It downgrades to a two lane rural road heading out of Greensboro, and again parallels north of I-40/I-85. Entering Alamance County, it expands to a four-lane expressway through the city of Burlington, then returns to 2 lanes through Mebane, Efland and Hillsborough. It joins I-85 briefly in Eno, then veers southeast through the downtown areas of both Durham and Raleigh. After a brief overlap with I-40 near Garner, it continues in a southeasterly direction, as it goes through or bypasses the cities of Clayton, Smithfield, Selma, Goldsboro and Kinston. Near and through New Bern, US 70 briefly becomes a freeway but returns to expressway grade as it goes through Havelock. After passing through Morehead City and Beaufort, it drops back to a two-lane rural road as it travels close along the Core Sound. After passing the southern terminus of NC 12 (which connects to the Outer Banks), near Sealevel, US 70 ends its seven state tour in the community of Atlantic.
