National Highways are major roads in a country that connect important cities and regions. They are designed to facilitate the movement of goods and people, playing a crucial role in a nation's transportation network. These highways are typically maintained by the national government and are built to higher standards than local roads. In many countries, National Highways are numbered for easy identification and navigation. They often feature multiple lanes, rest areas, and signage to ensure safety and efficiency. The development of National Highways can significantly boost economic growth by improving access to markets and reducing travel time.
