National Highways are the lifelines of India’s transport system, connecting states, cities, towns, and villages. They make travel faster, support trade, boost tourism, and play an important role in defense. Every state has its share of national highways, but one state stands out with the longest stretch, making it the most connected and crucial region in India’s road network.
India has the largest road network in the world, covering more than 6.6 million kilometers. With about 1.94 km of roads per square kilometer, its road density is higher than countries like the US, China, Brazil, and Russia. Roads in India carry nearly 71% of goods and about 85% of passenger traffic, making them the backbone of the nation’s transport system.
Maharashtra has the longest National Highway network in India, covering about 18,462 kilometers. Being one of the largest and most industrialized states, it requires strong connectivity to link its cities, ports, and industrial hubs. Highways in Maharashtra connect important places like Mumbai, Pune, and Nagpur with other parts of India. This vast road system supports trade, tourism, agriculture, and daily travel, making Maharashtra a leader in India’s road transport infrastructure.
Some Indian states have very long National Highway networks that connect cities, ports, and villages. States like Maharashtra, Uttar Pradesh, Rajasthan, and Madhya Pradesh lead the list with thousands of kilometers of highways.
