U.S. Route 70S (US 70S) is an alternative to U.S. Route 70 between the western part of Nashville and Sparta in Tennessee. It runs concurrent with US 70 for several blocks in downtown Nashville. The highway follows Murfreesboro Pike from Nashville to Murfreesboro then heads due east to McMinnville then northeast to Sparta where it ends at its junction with US 70. It was originally designated as U.S. Route 270 in 1926.
