SAIL’s Massive Steel Supply Powers Strategic Zojila Tunnel Project Significant

Authority of India Limited has become the largest supplier to the Zoila Tunnel project, India’s longest road tunnel and Asia’s longest bi-directional tunnel. With over 31,000 tonnes of steel supplied, commitment to the project is evident as it progresses towards its 2027 completion. The tunnel, located at an altitude of 11,578 feet, will provide vital all-weather connectivity between Srinagar and Lehi, enhancing civilian and military mobility. contribution to the Zoila Tunnel adds to India’s iconic infrastructure projects. As reported by (Business Standard), over 31,000 tonnes of steel have been supplied by SAIL for the Zoila Tunnel.

The Authority of India Limited has played a pivotal role in the ongoing construction of the Zoila Tunnel, supplying more than 31,000 tonnes of high-quality steel. As one of India’s most strategic and challenging infrastructure projects, the Zoila Tunnel, which connects Srinagar and Lehi year-round, is a vital initiative for regional connectivity and national security. The massive steel contribution by SAIL highlights its integral presence in India’s mega infrastructure undertakings.

Contribution to Strategic Infrastructure

SAIL’s has been used in the form of TMT bars, structural, and plates, all tailored to meet the stringent demands of high-altitude, cold-region tunnelling. The Zoila Tunnel, situated at an altitude of over 11,500 feet, faces extreme weather conditions, which demand materials of unmatched quality and durability. Rourkela and Bokaro steel plants have led the supply chain for this project. For more insights on similar projects, read our coverage on (Tunnel Projects).

Boost to Indigenous Manufacturing

This massive supply underlines India’s push for self-reliance in infrastructure through Atmanirbhar Bharat. By leveraging domestically produced steel, the project reduces reliance on imports and boosts indigenous manufacturing. SAIL’s consistent involvement in high-priority national projects underscores the company’s critical role in India’s infrastructure landscape.

Engineering and Safety Standards

The steel provided for the Zoila Tunnel meets all national and international quality certifications, reinforcing engineering integrity and worker safety. Given the tunnel’s importance to the Border Roads Organisation (BRO) and defence logistics, materials used must withstand not just time but also tectonic and climatic challenges. The advanced processing and quality control at SAIL facilities ensure these standards are consistently met.

Economic and Regional Impact

The Zoila Tunnel, once operational, is expected to significantly improve trade, transport, and emergency services between Jammu & Kashmir and Ladakh. SAIL’s involvement goes beyond supply—it is a boost to the local economy through employment, logistics support, and ancillary industries. By reducing travel time across the region, the tunnel will unlock new economic opportunities.

Future Outlook

As India accelerates its pace of infrastructure development, SAIL’s role continues to expand. From freight corridors to high-speed rail and coastal infrastructure, SAIL is positioned to be a steel backbone of modern India. The successful and timely supply to the Zoila Tunnel project adds yet another milestone to its growing portfolio. Visit our latest feature on to explore upcoming developments.
