India’s ambitious, strategic, all weather Zojila Tunnel in seismic Zone IV is set to witness its final breakthrough on June 9, 2026, with Union Minister for Road Transport and Highways Nitin Gadkari overseeing the last round of blasting from the Kargil side.
Mr. Gadkari will preside over the blasting of the final block, marking a key milestone in the execution of the project.
What is the Zojila Tunnel?
The 13.14 km tunnel cuts through the Himalayas at an altitude of 11,578 feet and connects the Kashmir Valley with Kargil in Ladakh.
The horseshoe shaped, single tube tunnel is 9.5 metres wide and 7.57 metres high, and is designed as a two lane road passage at an elevation of about 11,578 feet above sea level.
Located on the Srinagar Leh National Highway, the project is of considerable geostrategic significance. It is expected to provide all weather connectivity to Ladakh and reduce travel time from over an hour to about 15 minutes, officials said.
The tunnel runs from Baltal in Jammu and Kashmir’s Ganderbal district to Minimarg in the Drass sector of Ladakh, with an 18 km approach road. The overall project spans 31 km, including roads and bridges, from Sonamarg to Minimarg.
Megha Engineering and Infrastructure Limited (MIEL) is executing the project using the New Austrian Tunnelling Method to navigate the region’s fragile geological conditions.
Advanced safety features
The tunnel incorporates advanced safety systems, including a semi transverse ventilation mechanism to ensure steady airflow.
It is equipped with a Smart Tunnel system based on SCADA, along with CCTV surveillance, radio control, uninterrupted power supply and ventilation systems.
Once operational, it will improve civilian and military mobility across the Zojila Pass, which remains closed for nearly three months each winter due to heavy snowfall.
Strategic significance
The Zojila Tunnel, regarded as one of the longest single tube bi-directional road tunnels at this altitude, is expected to be a strategic asset for Ladakh, which lies between Pakistan to the west and China to the east.
The region assumed heightened importance after the Kargil conflict of 1999 and subsequent tensions along the Line of Actual Control, including the 2020 stand off.
Limited connectivity during winter months has historically posed challenges for logistics and deployment. The tunnel is part of a broader effort to create multiple strategic access routes to Ladakh. These include the Rohtang corridor linking Himachal Pradesh, the proposed connectivity through the Zanskar region, and the Zojila axis connecting Jammu and Kashmir.
Together, these corridors are expected to strengthen military mobility and logistical preparedness.
All weather connectivity
The tunnel bypasses the Zojila Pass, which is prone to landslides and rockfall and remains inaccessible in winter.
During the Kargil conflict, the Srinagar Kargil highway was vulnerable to shelling, particularly in the Drass sector. This affected the movement of troops and supplies during the 53 day conflict.
Efforts to improve alternative access, including the Ladakh Himachal axis, have helped but remain season dependent, typically opening in May and closing by November.
The Zojila Tunnel is expected to address this limitation by ensuring uninterrupted connectivity throughout the year.
Reduced travel time and logistics support
The project, estimated to cost over ₹6,800 crore, will significantly cut travel time between Ganderbal and Kargil from about three hours to around 20 minutes, officials said.
The tunnel infrastructure includes four culverts, four Nilgrar tunnels, eight cut and cover sections and a vertical ventilation shaft of about 220 metres. The western portal is located at Baltal and the eastern portal at Minimarg.
Once operational, the tunnel is expected to facilitate year round transport of supplies to high altitude areas in Ladakh. At present, provisions for winter months are largely pre positioned in advance ahead of snowfall.
Security forces in Ladakh depend heavily on surface connectivity for the movement of goods and personnel. The project lies along National Highway 1, with elevations ranging from about 2,700 metres to 3,300 metres, linking Sonamarg in Jammu and Kashmir to Minimarg in Ladakh.
