The term "Federal Highway" refers to a network of roads and highways in the United States that are funded and maintained by the federal government. These highways are crucial for facilitating interstate travel and commerce, connecting cities and regions across the country. The Federal Highway Administration (FHWA) oversees the planning, construction, and maintenance of these roads, ensuring they meet safety and quality standards. Federal highways are part of the larger National Highway System, which includes major routes that are vital for economic activity and mobility. They are designed to accommodate a high volume of traffic and often feature multiple lanes, interchanges, and other infrastructure to support efficient transportation.
