Major highways are large, well-maintained roads designed for long-distance travel and efficient transportation of goods and people. They often connect cities, regions, and states, facilitating commerce and tourism. These highways typically have multiple lanes, limited access points, and higher speed limits compared to local roads, making them essential for quick travel. In many countries, major highways are part of a national or regional network, such as the Interstate Highway System in the United States or the Autobahn in Germany. They are crucial for economic development, as they support trade and provide access to various services and attractions along their routes.
