Interstate Highways

Interstate Highways are a network of major roads in the United States designed for fast, efficient travel between cities and states. They are part of the Interstate System, marked by shield-shaped signs with a numbered route, usually with multiple lanes and limited access points to reduce delays. These highways support commerce, emergency response, and everyday transportation, facilitating smooth movement of vehicles over long distances. They are federally funded and maintained, ensuring consistent standards, safety, and connectivity across the country.
