Indian highways are a network of major roads that connect different states and cities across India. They play a crucial role in facilitating transportation and trade, allowing for the movement of goods and people. The National Highways Authority of India (NHAI) is responsible for the development and maintenance of these highways, ensuring they meet safety and quality standards. The Indian highway system includes over 150,000 kilometers of roads, with many being four-lane or six-lane expressways. These highways are vital for economic growth, reducing travel time, and improving access to remote areas. They also support tourism by linking popular destinations throughout the country.
