The National Highways of India are a network of major roads that connect different states and regions across the country. These highways are crucial for facilitating trade, transportation, and travel, playing a vital role in India's economic development. Managed by the Ministry of Road Transport and Highways, they cover over 150,000 kilometers. These highways are designed to support heavy traffic and are built to high standards. They often feature multiple lanes, bridges, and tunnels, ensuring efficient movement of goods and people. The National Highways Authority of India oversees the maintenance and development of this essential infrastructure.
