State Route 448 (SR-448) is a state highway located completely within the city of Sevierville in Sevier County, within the eastern part of the U.S. state of Tennessee. 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 SR-66.
