U.S. Route, also known as U.S. Highway, is a network of roads that spans across the United States. Established in 1926, these routes are numbered highways that connect major cities, towns, and regions. They are maintained by state and local governments and serve as important corridors for transportation and commerce. The U.S. Route system includes famous highways like U.S. Route 66, often referred to as the "Main Street of America." These routes are marked with distinctive white signs featuring black numbers, making them easy to identify for travelers. The system plays a crucial role in American history and culture, facilitating road trips and cross-country travel.
