The U.S. Route System is a network of highways that connects cities and towns across the United States. Established in 1926, it includes numbered routes that help travelers navigate the country. Each route has a unique number, making it easier for drivers to find their way. These highways are often marked with distinctive U.S. Route signs, featuring a white shield with a black number. The system has played a crucial role in American transportation, allowing for the movement of goods and people. Many famous routes, like Route 66, have become iconic symbols of American road trips and adventure.
