The 13.153-km Zojila Tunnel, the world's longest single-tube bi-directional road tunnel at the highest altitude, and its final breakthrough is a historic milestone in India's infrastructure history.
Located in the Zojila region between Baltal (Sonamarg) and Meenamarg (Drass and Kargil) in the Union Territories of Jammu and Kashmir and Ladakh, the project is being executed to provide all‑weather connectivity across one of India's most challenging Himalayan corridors, which remains cut off for long periods every year due to heavy snowfall, avalanches, and extreme weather conditions.
Positioned at an elevation of about 11,578 feet above sea level, the tunnel represents one of the most significant engineering achievements in India's mountain infrastructure sector.
The engineering feat is set to improve all-weather connectivity between Kashmir and Ladakh.
