Hyderabad, July 20 (Maxim News): In a remarkable contribution to India’s strategic infrastructure, Steel Authority of India Limited (SAIL) has emerged as the largest steel supplier to the Zojila Tunnel, India’s longest under-construction road tunnel and Asia’s longest bi-directional tunnel. With more than 31,000 tonnes of steel supplied — including TMT Re-bars, Structurals, and Plates — SAIL continues to demonstrate its central role in building the nation’s backbone.
The Zojila Tunnel, stretching over 30 kilometers through the treacherous Himalayan terrain at an altitude of 11,578 feet, is a critical part of the Srinagar-Kargil-Leh National Highway. Upon its completion in 2027, the tunnel will offer year-round, all-weather connectivity between Srinagar and Leh, significantly boosting both civilian and military mobility in Jammu & Kashmir and Ladakh.
SAIL’s Enduring Commitment to Infrastructure Development
As a Maharatna Public Sector Undertaking, SAIL’s partnership in this ambitious project reinforces its status as India’s most trusted steelmaker. The consistent supply of high-grade steel for the Zojila Tunnel mirrors SAIL’s longstanding legacy in nation-building. The company’s products are known for their strength, reliability, and quality — making them the material of choice for iconic mega-projects.
SAIL has previously contributed to several prestigious projects, including:
- Chenab Railway Bridge – the world’s highest railway bridge
- Atal Tunnel – the longest highway tunnel above 10,000 ft
- Bandra-Worli Sea Link
- Dhola Sadiya and Bogibeel Bridges

Zojila Tunnel: A Strategic and Economic Lifeline
Beyond its engineering marvel, the Zojila Tunnel will serve as a lifeline for economic and regional development. By ensuring year-round access to remote and strategic regions like Kargil and Leh, the tunnel will facilitate trade, tourism, and rapid deployment of defense forces if required.
The tunnel’s construction is a strategic game-changer for India’s connectivity goals and defense preparedness, and SAIL’s contribution is pivotal in ensuring timely and durable infrastructure delivery in this high-stakes project.
