East Parkway north to Summer Avenue, where the triple concurrency turns east. Near the city line, US 64/70/79 interchanges with Interstate 40 at exit 12A. Past the Memphis city limits in the suburb of Bartlett, U.S. 64 separates from U.S. 70/79, taking a more southerly routing through the state. U.S. 70 and US 79, meanwhile, head to the northeast, paralleling I-40 to Brownsville. East of the city, U.S. 79 breaks from U.S. 70, following U.S. 70 Alternate out of the city to the northeast. U.S. 70, now concurrent with only its unsigned designation of State Route 1, heads east, interchanging with I-40 at exit 66 before entering Jackson. The route continues northeastward from the city, meeting I-40 once more at exit 87 just outside the city limits. At Huntingdon, U.S. 70 Alternate rejoins US 70 as the main route turns to the east toward New Johnsonville, where it crosses the Tennessee River. From the river, U.S. 70 continues eastward through Waverly and Dickson to the Nashville area. Southwest of the city near Pegram, U.S. Route 70S splits off from U.S. 70; however, U.S. 70 now continues to be signed as U.S. 70 instead of U.S. 70N, as it was formerly. U.S. 70 follows I-40 into Nashville, meeting the concurrent I-40/I-65 immediately west of the city center. The route turns south, acting as collector/distributor roads for I-40/I-65 for two blocks before joining U.S. 431 and U.S. 70S on a brief overlap. At an intersection with the concurrent U.S. 31/U.S. 41, U.S. 431 and U.S. 70S split from U.S. 70. U.S. 70 progresses eastward, roughly paralleling the Cumberland River to an interchange with State Route 155 east of downtown. U.S. 70, now paired with State Route 24, heads east out of Nashville to Lebanon, where U.S. Route 70N breaks from the main US 70. US 70 heads southeast, passing through Smithville before rejoining U.S. 70S in Sparta and U.S. 70N to the east in Crossville. From Crossville eastward to the North Carolina state line, U.S. 70 closely parallels I-40, passing through the Roane County cities of Rockwood and Kingston. At Dixie Lee Junction in eastern Loudon County U.S. 70 intersects U.S. 11 (also known as the Lee Highway) in Dixie Lee Junction and the two highways are concurrent from the junction intersection eastward through Farragut and into Knoxville. In Farragut and west of downtown Knoxville U.S. 70 carries the name Kingston Pike.
