India breaks final rock of Zojila Tunnel in Himalayas

Zojila Tunnel: 13 km long, India’s longest, costing $712 million, opening in 2028

India continues developing infrastructure projects in the northern mountainous regions as part of plans to enhance land and logistical connectivity between high-altitude areas and vital centers, amid complex geographical and climatic challenges in the Himalayan region.

Engineering Milestone at Zojila Tunnel

Indian engineers announced on Tuesday the completion of the final rock section breakthrough of the strategic Zojila Tunnel, which is considered one of the most important infrastructure projects in the Himalayan mountain range, aiming to ensure year-round connectivity between the regions of Kashmir and Ladakh.

Indian Minister of Road Transport Nitin Gadkari said during a partial opening ceremony for the project that the tunnel is “not just a tunnel, but a lifeline,” referring to its role in facilitating movement and transport between the northern mountainous regions.

Meanwhile, the project’s engineer, Manmohan Singh, explained that the excavation work was carried out in difficult climatic and geographical conditions, confirming that the project was completed “without any notable incidents.”

Strategic Project to Connect Kashmir and Ladakh

The Zojila Tunnel is part of a broader project aimed at enhancing connectivity between Srinagar, the summer capital of the Indian-administered region of Kashmir, and the city of Leh in the Ladakh region bordering China.

The current road between the two cities is among the most affected by snowfall during winter, leading to prolonged disruption of land traffic, which makes the tunnel a pivotal project for ensuring year-round transport.

The project also falls within a broader plan to develop the transport network, including roads and railways, enabling the transport of goods, military supplies, and civilian cargo to the high-altitude regions of the Himalayas.

Project Details and Cost

The Zojila Tunnel extends more than 13 kilometers, with an estimated cost of $712 million, involving more than 3,000 workers since work began in 2020.

The tunnel is scheduled to open to traffic in 2028, making it one of the longest operational mountain tunnels in India.

The project is also integrated with a network of other tunnels, including the 6.5-kilometer Sonamarg Tunnel, in addition to the Chenab River railway bridge project, which is considered one of the highest bridges in the world.

India had previously opened a 272-kilometer railway line in June 2025, connecting the city of Udhampur to Kashmir’s cities via Srinagar.

Regional Dimensions and Border Context

These projects come within a sensitive regional context, as the border between India and China, extending approximately 3,500 kilometers, witnesses recurring tensions despite relative improvement in relations in recent years.

In 2020, the Himalayan region witnessed a border clash that resulted in fatalities on both sides, reflecting the continued sensitivity of the border situation between the two countries.

Meanwhile, the Kashmir region remains a long-standing conflict zone between India and Pakistan since 1947, with each party claiming full sovereignty over it.

Future Strategic Importance

The Zojila Tunnel is expected to enhance logistical connectivity between mountainous regions, including facilitating the transport of supplies, goods, and reinforcements through the road and rail transport network linked to the project.

The project is seen as part of a broader Indian strategy to strengthen infrastructure in border areas with difficult geographical terrain, ensuring uninterrupted movement throughout the year.
