Route description
SR 338 begins at an intersection with US 441/US 411/SR 35/SR 71 in Seymour. It winds its way northeast as Boyds Creek Highway to pass through Boyds Creek before entering Sevierville and coming to an intersection with SR 66 and the Great Smoky Mountains Parkway. SR 338 turns south and becomes concurrent with SR 66 to pass through a business district before leaving SR 66 and turning northeast onto Douglas Dam Road and leaving Sevierville. It continues northeast through farmland to pass through Alder Branch, where it becomes Old State Highway 66, before turning north and crossing the French Broad River just west of the Douglas Dam. SR 338 then continues north to come to an end at an intersection with SR 139.
