U.S. Route 70N (US 70N) is a northern alternate to U.S. Route 70. It runs east–west from Lebanon to Crossville, connecting the cities of South Carthage, Baxter, Cookeville, and Monterey.
US-70N is a predominantly two-lane rural highway, with divided-four lanes at major intersections only. The route begins in Lebanon, where it goes northeasterly to Carthage. After crossing the Caney Fork, the route goes along and through various ridges before reaching Cookeville. After its first cross across Interstate 40 (exit 290), it goes south into Dry Valley; from there it goes northeasterly back to parallel Interstate 40 to Monterey. In Monterey, US-70N crosses Interstate 40 its second (exit 300) and third time (exit 301). Going southeast, to meets back with US-70, in Crossville.
The entire route is in concurrency with SR-24; which is recognized as a primary route between Lebanon and Cookeville, and secondary between Cookeville and Crossville. It also follows closely to Interstate 40, which is a faster and more preferable route for travelers.
