US 25W has been included in the U.S. Highway System since the system's inception in 1926.
US 25W and US 25E splits at Newport, Tennessee. While US 25E goes on a northerly path towards Morristown, US 25W goes more of a westerly path to cross I-40, and to go through Dandridge, and cross I-40 for a second time. For all of its course from Newport to the east side of Knoxville, it runs concurrently with US 70. It then runs concurrently with I-640 for about two-thirds of its course around the city. It departs I-640 and the city of Knoxville, and goes furthern northwest to Clinton, in Anderson County. It goes on a concurrent run with I-75 from Rocky Top (formerly Lake City) into Campbell County. It then goes through the towns of LaFollette and Jellico. US 25W carries the secret designation of Tennessee State Route 9 for its entire course through the state.
Upon entry into Whitley County, Kentucky, US 25W runs parallel with and closely follow I-75 for the rest of its course, including the points where it traverses the towns of Williamsburg and Corbin. It terminates at North Corbin, where US 25E and US 25W reunites to become US 25 north of Corbin. However, US 25E continues west of this point to terminate at exit 29 of I-75 in southern Laurel County.
US 25W originally ran the current routing of Kentucky Route 26, and KY 90 terminated in downtown Corbin. KY 26 originally ran to KY 90 west of Corbin. At sometime in the 1940s, US 25W was rerouted to its current alignment to provide easier access to Cumberland Falls, and KY 26 ran US 25W's original course between Corbin and Williamsburg.
