The strategic Zojila Tunnel, which will provide all-weather connectivity between Kashmir and Ladakh, is set to significantly enhance military logistics for the Army and the Indian Air Force (IAF) in the sensitive border region.
Once operational, the tunnel will streamline the movement of troops and supplies throughout the year. At present, road connectivity to Ladakh is severely affected during winter months, when heavy snowfall leads to the closure of key routes. Even during summer, when the Zojila Pass remains open, Army supply convoys take three to four hours to negotiate the stretch because of steep gradients and difficult terrain. The tunnel is expected to reduce travel time across the pass to just 30-40 minutes.
More than 70,000 Army personnel are deployed in Ladakh, while the IAF operates helicopter units and radar installations in the region. The Indo-Tibetan Border Police (ITBP) also maintains a significant presence along the frontier.
Currently, both road routes to Ladakh remain closed for several months during winter. During this period, troops and fresh supplies such as fruits and vegetables are airlifted by military aircraft operating from Chandigarh. However, heavy equipment, vehicles, armoured platforms, machinery, fuel, spares and dry rations have to be stocked in advance during the summer months.
Ladakh shares an 823-km frontier with China and remains strategically important for India’s military posture along the Line of Actual Control (LAC). For more than four months each year, both the 434-km Srinagar-Sonamarg-Leh route and the 475-km Manali-Keylong-Leh route remain closed due to heavy snowfall.
While the Manali-Leh axis benefits from the Atal Tunnel beneath the Rohtang Pass, the route still traverses high-altitude passes such as Baralacha Pass (16,040 feet), Lachung La (16,800 feet) and Tanglang La (17,480 feet), which are frequently blocked by snow.
On June 9, the Zojila Tunnel project achieved its final breakthrough as engineers blasted the last remaining rock barrier, linking the two ends of the tunnel and paving the way for rapid, all-weather connectivity between Kashmir and Ladakh. The milestone also marked the completion of tunnelling work that began in October 2020.
The significance of the road network leading to Ladakh has grown considerably since April 2020, when Indian and Chinese troops were locked in a military standoff along the Line of Actual Control in eastern Ladakh.
