India is making significant strides in tunnelling infrastructure, with around 240 km of tunnels being built or planned across challenging terrains.

The expansion of road, rail, and urban tunnelling projects aims to improve connectivity, strategic mobility, and freight movement. Tunnelling has become one of the fastest-growing infrastructure sectors, driven by border road development, railway expansion, and metro networks. Notable projects include the Atal Tunnel, the world’s longest highway tunnel above 10,000 ft., which reduces travel time between Manali and Sarchu by four to five hours. "These tunnels enhance year-round connectivity, boosting both civilian and defence movement," said a government spokesperson.

Another key project, the 12-km Sonamarg Tunnel, will help alleviate winter closures in Jammu and Kashmir. India's railway tunnelling, including the 12.77-km Tunnel T50, is also advancing, with new urban and high-speed projects like the Kolkata underwater Metro tunnel and the Mumbai–Ahmedabad bullet train. The upcoming Zojila Tunnel, set to be India’s longest, will further boost regional connectivity.
