Tennessee State Route 448 is a route located completely within the city of Sevierville in Sevier County, Tennessee. It runs north from U.S. 411, crosses the East Prong of the Little Pigeon River, turns west, and ends at Tennessee State Route 66. It is more commonly known as North Parkway. There are three northbound lanes, a center turn lane, and one southbound lane. This is in order to accommodate for the traffic heading north out of the busy tourist area, since the majority of the southbound traffic enters via TN 66. The posted speed limit is 30 MPH. The entirety of the route carries the east branch of the Great Smoky Mountains Parkway.
