Breakthrough blast of Zojila Tunnel

Why in News?

The Union Minister for Road Transport and Highways recently witnessed the historic breakthrough of the main tunnel at the eastern portal of the Zojila Tunnel Project at Minamarg in Kargil district. The breakthrough marks a major milestone in the construction of one of India’s most ambitious high-altitude tunnel infrastructure projects.

About the Zojila Tunnel Project

The Zojila Tunnel is being constructed between Baltal and Minamarg on National Highway-1 (NH-1). The tunnel is being developed at an estimated cost of approximately ₹6,800 crore and is located at elevations ranging from about 2,900 metres to 3,310 metres above sea level.

The tunnel passes through the strategically important Zojila Pass, which connects the Kashmir Valley with the Ladakh region.

Key Features

The Zojila Tunnel is a nearly 14-kilometre-long bi-directional tunnel, making it one of the longest road tunnels in India. The project is being constructed in one of the world’s most challenging mountain terrains and at an elevation of around 11,578 feet.

The tunnel is designed to provide all-weather connectivity between the Union Territories of Jammu & Kashmir and Ladakh. 

Upon completion, the tunnel will significantly reduce travel time between key locations in the region.

• Travel time between Sonamarg and Minamarg will decrease from nearly two hours to about 30 minutes.
• Travel time between Ganderbal and Kargil will be reduced from around three hours to just over 20 minutes.

The project will also lead to substantial savings in fuel consumption and transportation costs. 

The tunnel will ensure year-round connectivity to the Ladakh region, which often remains cut off during winter due to heavy snowfall and closure of the Zojila Pass.

The project is of immense strategic significance as it will improve the movement of civilians, goods, and defence personnel in a sensitive border region. 

The tunnel is expected to reduce accidents and travel disruptions caused by avalanches, landslides, heavy snowfall, and adverse weather conditions. Improved connectivity is also likely to boost tourism, trade, economic development, and regional integration in the Himalayan region.
