Auto trail in the context of "U.S. Route 1 in Virginia"

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.

Dixie Highway was a United States auto trail first planned in 1914 to connect the Midwest with the South. It was part of a system and was expanded from an earlier Miami to Montreal highway. The final system is better understood as a network of connected paved roads, rather than one single highway. It was constructed and expanded from 1915 to 1929.

The Dixie Highway was inspired by the example of the slightly earlier Lincoln Highway, the first road across the United States. The prime booster of both projects was promoter and businessman Carl G. Fisher. It was overseen by the Dixie Highway Association and funded by a group of individuals, businesses, local governments, and states. In the early years, the U.S. federal government played little role, but from the early 1920s on it provided increasing funding until 1927. That year the Dixie Highway Association was disbanded and the highway was taken over by the federal government as part of the U.S. Route system, with some portions becoming state roads.

Interstate 5 (I-5) is the main north–south Interstate Highway on the West Coast of the United States, running largely parallel to the Pacific coast of the contiguous U.S. from Mexico to Canada. It travels through the states of California, Oregon, and Washington, serving several large cities on the West Coast, including San Diego, Los Angeles, Sacramento, Portland, and Seattle. It is the only continuous Interstate highway to touch both the Mexican and Canadian borders. Upon crossing the Mexican border at its southern terminus near San Diego, the highway continues to Tijuana, Baja California as Mexican Federal Highway 1 (Fed. 1). Upon crossing the Canadian border at its northern terminus in Blaine, Washington, it continues to Vancouver, British Columbia as British Columbia Highway 99 (BC 99).

I-5 was originally created in 1956 as part of the Interstate Highway System, but it was predated by several auto trails and highways built in the early 20th century. The Pacific Highway was built in the 1910s and 1920s by the states of California, Oregon, and Washington, and was later incorporated into U.S. Route 99 (US 99) in 1926. I-5 largely follows the route of US 99, with the exception of portions south of Los Angeles and in the Central Valley of California. The freeway was built in segments between 1956 and 1978, including expressway sections of US 99 that were built earlier to bypass various towns along the route. US 99 was removed in 1972.

The Lee Highway was a United States auto trail through the American South and Southwest. When opened in 1923, it connected Washington, D.C., and San Diego, California; extensions were later added to New York and San Francisco.

The route was created to be a Southern complement to the Lincoln Highway, the nation's first transcontinental auto route. It was named for Confederate general Robert E. Lee as part of a broad effort to present Confederate actions during the American Civil War as just, heroic, and not centered on slavery.
