U.S. Route 70 (US 70) enters the state of Tennessee from Arkansas via the Memphis & Arkansas Bridge in Memphis, and runs west to east across 21 counties in all three Grand Divisions of Tennessee, with a total length of , to end at the North Carolina state line in eastern Cocke County. Along the route, US 70 is accompanied with various U.S. and state highways, including those in three of the state's four major cities (e.g. Memphis, Nashville, and Knoxville). Route description Memphis to Nashville US 70 enters the state via the Memphis & Arkansas Bridge on I-55, along with U.S. Routes 61, 64, and 79, along with SR 1. US 70 follows E.H. Crump Avenue, Danny Thomas Boulevard, Union Avenue, East Parkway, and Summer Avenue through Memphis, mostly accompanied with US 64 and US 79, along with some of SR 3. While US 64 departs from US 70/79 in Bartlett, US 79 remains with US 70 from there to Brownsville, in Haywood County. US 70 turns eastward to go through the cities of Jackson, Huntingdon, and Camden before crossing the Tennessee River. After that, it then continues eastward through Waverly, Dickson, and Kingston Springs before making entry into Nashville.

US 70 has two concurrencies with SR 1 in the western half of the state, one in the downtown area, and the other from the east side of Memphis to western Davidson County. The brief one in downtown Nashville is the third SR 1 concurrency along with US 70S/US 431 along Broadway.

US 70 continues into downtown Nashville, following Charlotte Avenue, 14th Avenue (13th Avenue for US 70's westbound lanes along I-40/I-65), Broadway, First Avenue, and Hermitage Avenue. At the 14th Avenue intersection on Charlotte Avenue, US 70 acts 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. After US 431 and US 70S splits from the main route on Broadway, US 70 progresses eastward, roughly paralleling the Cumberland River, ducking under the western split of I-40 and I-24, and continuing to
