Upon entering Sevierville, the parkway splits into an east and west branch, which together encircle the business district of Sevierville, as well as a spur in both directions along U.S. 411. Northbound traffic is directed along the east branch, which contains three northbound lanes and one southbound lane, and southbound traffic along the west branch, which contains three southbound lanes and one northbound lane. In this split section, both north and southbound lanes intersect with US 411, where US 441 splits of into a concurrency with US 411 to the east. At this intersection, the parkway becomes part of SR 66, and is known as Winfield Dunn parkway.
