The Foothills Parkway is a National Parkway which, if completed, will traverse the foothills of the northern Great Smoky Mountains in East Tennessee, located in the Southeastern United States. The 71-mile (114 km) parkway will ideally connect U.S. Route 129 (US-129) along the Little Tennessee River in the west with Interstate 40 (I-40) along the Pigeon River in the east, passing through parts of Blount, Sevier, and Cocke counties.
