India’s road network is the backbone of its economic growth, trade, and connectivity. It is the second-largest in the world, stretching across cities, towns, villages, and even remote rural areas. Highways, in particular, form the lifelines that connect industrial hubs, agricultural belts, and tourism zones.
In 2025, several Indian states have taken the lead in expanding their highway systems, creating some of the most extensive road networks in the country. These highways include National Highways (NH) maintained by the central government and State Highways (SH) maintained by respective state governments. Together, they enable smooth movement of goods and people across thousands of kilometers.
