The U.S. Highway System, established in 1926, is a network of roads that connects cities and regions across the United States. It includes numbered highways, which are designed for long-distance travel and efficient transportation of goods. The system is maintained by state and federal governments, ensuring safe and reliable travel for millions of drivers each year. The highways are categorized into two main types: Interstate Highways, which are part of the National Interstate and Defense Highways Act of 1956, and U.S. Routes, which are older and often run through towns and cities. Together, they facilitate commerce and tourism, playing a vital role in the nation's economy.
