The Zojila Tunnel, located in the Union Territory of Ladakh, India, is being developed as Asia’s longest bi-directional road tunnel upon completion. It forms a crucial part of the NH-1 project and will connect Srinagar with Leh.

Built at an altitude of around 11,578 feet, the tunnel is designed to ensure all-weather connectivity between Sonmarg in Jammu & Kashmir and Drass in Ladakh, a route that is otherwise blocked during winters due to heavy snowfall.

With an approximate length of 13.14 kilometers, it is set to become the longest road tunnel in Asia.

The project holds strategic significance for India, as it strengthens connectivity in a region that is important both militarily and economically. Construction began in 2020 and is expected to be completed by 2026, aiming to enhance access to Ladakh and support its socio-economic development.
