Major Highways, Bridges, Tunnels & Infrastructure

India's modern engineering projects encompass record-breaking bridges, high-altitude mountain tunnels, and access-controlled expressways that transform regional connectivity. Notable transport milestones include the Atal Tunnel at Rohtang (9.02 km), which is one of the world's longest single-tube highway tunnels above 10,000 feet, and the Zojila Tunnel under construction in Ladakh. In bridge engineering, the Dhola-Sadiya Bridge (Bhupen Hazarika Setu, 9.15 km) over the Lohit River in Assam is India's longest water bridge, while the Chenab Rail Bridge in Jammu and Kashmir is the world's highest railway arch bridge, standing 359 meters above the riverbed. Major expressways like the Mumbai-Nagpur Samruddhi Mahamarg and Delhi-Mumbai Expressway lead modern highway development.
