What is Zojila Tunnel? All you need to know about the all weather tunnel in Ladakh
India’s IV. The ambitious, strategic and all-weather Zojila Tunnel in the Seismic Zone will witness its final thrust on June 9, 2026, when Union Minister for Road Transport and Highways Nitin Gadkari will oversee the final round of blasting by Kargil.
Mr. Gadkari will preside over the blasting of the last block, which is a major milestone in the execution of the project.
What is Zojila Tunnel?
The 13.14-kilometer tunnel cuts through the Himalayas at an altitude of 11,578 feet and connects the Kashmir Valley to Kargil in Ladakh.
The horseshoe-shaped single tube tunnel is 9.5 meters wide and 7.57 meters high and is designed as a two-lane road crossing at approximately 11,578 feet above sea level.
Located on the Srinagar Leh National Highway, the project has significant geostrategic importance. All-weather connectivity to Ladakh is expected to be provided and travel time will be reduced from one hour to around 15 minutes, officials said.
The tunnel extends from Baltal in Ganderbal district of Jammu and Kashmir to Minimarg in Drass sector of Ladakh via an approach road of 18 km. The entire project covers an area of 31 km, including roads and bridges, from Sonamarg to Minimarg.
Megha Engineering and Infrastructure Limited (MIEL) is executing the project using the New Austrian Tunneling Method to navigate the sensitive geological conditions of the region.
Advanced security features
The tunnel contains advanced safety systems, including a semi-transverse ventilation mechanism to ensure constant airflow.
It is equipped with a SCADA-based Smart Tunnel system as well as CCTV surveillance, radio control, uninterruptible power supply and ventilation systems.
Once operational, it will increase civilian and military mobility in the Zojila Pass, which remains closed for about three months every winter due to heavy snowfall.
strategic importance
Considered one of the longest single-tube two-way highway tunnels at this height, Zojila Tunnel is expected to be a strategic asset for Ladakh, located between Pakistan in the west and China in the east.
The region assumed further importance after tensions along the Line of Actual Control, including the Kargil conflict in 1999 and the subsequent standoff in 2020.
Limited connectivity during the winter months has historically caused logistics and distribution challenges. The tunnel is part of a broader effort to create multiple strategic access routes to Ladakh. These include the Rohtang corridor connecting Himachal Pradesh, the proposed link via Zanskar region and the Zojila axis connecting Jammu and Kashmir.
Together, these corridors are expected to strengthen military mobility and logistics readiness.
Connection in all weather conditions
The tunnel passes next to the Zojila Pass, which is prone to landslides and rockfalls and is inaccessible in winter.
During the Kargil conflict, the Srinagar Kargil highway was vulnerable to shelling, especially in the Drass area. 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 seasonally dependent; It usually opens in May and closes in November.
Zojila Tunnel is expected to overcome this limitation by providing uninterrupted connectivity throughout the year.
Less travel time and logistics support
The project, estimated to cost over ₹6,800 crore, will significantly reduce travel time between Ganderbal and Kargil from around three hours to around 20 minutes, officials said.
The tunnel infrastructure consists of four culverts, four Nilgrar tunnels, eight cut-and-cover sections and approximately 220 meters of vertical ventilation shafts. The western portal is located in Baltal and the eastern portal is in Minimarg.
Once operational, the tunnel is expected to facilitate year-round transportation of materials to high-altitude regions of Ladakh. Currently, preparations for the winter months are largely pre-positioned ahead of snowfall.
Security forces in Ladakh largely depend on surface connectivity for movement of goods and personnel. The project is located on National Highway 1, which connects Sonamarg in Jammu and Kashmir to Minimarg in Ladakh, with elevations ranging from approximately 2,700 to 3,300 metres.
