A National Highway is a major road in a country that connects important cities and regions. These highways are typically maintained by the national government and are designed to facilitate long-distance travel and transport of goods. They often feature multiple lanes, higher speed limits, and better infrastructure compared to local roads. In many countries, National Highways play a crucial role in the economy by linking industrial areas with markets. They also enhance accessibility to remote areas, improving overall connectivity. These highways are essential for both personal travel and commercial transportation, contributing to national development.
