North Corbin, Kentucky in the context of "U.S. Route 25W"

U.S. Route 25E (US 25E) is the eastern branch of US 25 from Newport, Tennessee, where US 25 splits into US 25E and US 25W, to North Corbin, Kentucky, where the two highways rejoin. The highway, however, continues as US 25E for roughly two miles (3.2 km) until it joins Interstate 75 (I-75) in the Laurel County community of North Corbin at exit 29. The highway serves the Appalachia regions of Kentucky's Cumberland Plateau and the Ridge-and-Valley section of East Tennessee, including the urbanized areas of Corbin and Middlesboro in Kentucky and Morristown in Tennessee.

US 25E follows the original pathway of early U.S. pioneer Daniel Boone's Wilderness Road, which contributed to the increased settlement of Appalachia given its access through the rugged Cumberland Gap. By 1815, the route became the first state-funded road in Tennessee and, in 1923, unsigned State Route 32 (SR 32) in the Tennessee State Route System in its statewide entirety. It would be recognized as part of the Dixie Highway, one of the earliest federal auto trails, in 1915. The route was officially established as US 25E with the creation of the U.S. Numbered Highway System in 1926.

Some U.S. Routes are given directional suffixes to indicate a split of the main route — for instance, U.S. Route 25 (US 25) splits into US 25E (east) and US 25W (west) between Newport, Tennessee, and North Corbin, Kentucky, and US 9W is an alternate of U.S. Route 9 between Fort Lee, New Jersey, and Albany, New York. These splits were in the U.S. Highway system from the beginning, and were used when two roughly-equivalent routes existed. The American Association of State Highway and Transportation Officials (AASHTO) no longer assigns these numbers, and, in theory, current ones are to be eliminated "as rapidly as the State Highway Department and the Standing Committee on Highways can reach agreement". This policy was adopted by 1996; however, many of these routes still exist, mostly in Tennessee.

U.S. Route 25 or U.S. Highway 25 (US 25) is a north–south United States Numbered Highway that runs for 750 miles (1,210 km) in the Southern and Midwestern U.S. Its southern terminus is in Brunswick, Georgia, from where it proceeds mostly due north, passing through the cities of Augusta, Georgia; Greenville, South Carolina; and Asheville, North Carolina, before dividing into two branches, known as US 25W and US 25E between Newport, Tennessee, and North Corbin, Kentucky. After passing through Richmond and Lexington, Kentucky, it reaches its northern terminus at Ohio state line in Covington, Kentucky. The route is an important crossing of the Appalachian Mountains, and it is covered by three of the corridors of the Appalachian Development Highway System (ADHS). When the highway was originally established in 1926, the route extended from North Augusta, South Carolina, to Port Huron, Michigan. The southern end was extended to its current terminus in 1936, while the northern end was truncated in 1974.

Harland David Sanders (September 9, 1890 – December 16, 1980) was an American entrepreneur and founder of fast food chicken restaurant chain Kentucky Fried Chicken, now known as KFC. He later acted as the company's brand ambassador and symbol. His name and image are still symbols of the company today.

Sanders held a number of jobs in his early life, such as steam engine stoker, insurance salesman, and filling station operator. He began selling fried chicken from his roadside restaurant in North Corbin, Kentucky, during the Great Depression. During that time, Sanders developed his "secret recipe" and his patented method of cooking chicken in a pressure fryer. Sanders recognized the potential of the restaurant franchising concept, and the first KFC franchise opened in South Salt Lake, Utah, in 1952. When his original restaurant closed, he devoted himself full-time to franchising his fried chicken throughout the country.
