U.S. Highway System

The U.S. Highway System is a network of roads established to connect cities, towns, and regions across the United States. It includes primary routes, labeled with numbers (like U.S. Route 66), and smaller spur or auxiliary routes. These highways facilitate transportation and commerce by providing dependable, long-distance connections outside of local streets and state roads. They are maintained by the federal government and individual states, ensuring navigability and safety for travelers. The system complements the Interstate Highway System and is essential for regional travel, freight movement, and daily commuting across the country.
