Historic Breakthrough Approaches
India’s longest road tunnel at Zojila, valued at ₹6,500 crore, is on the verge of a historic milestone. Scheduled for a ceremonial event on June 9, Union Minister Nitin Gadkari will witness the breakthrough blast, marking the meeting of excavation faces from both ends of the tunnel. The Zojila Tunnel, constructed by Hyderabad-based Megha Engineering and Infrastructure Ltd (MEIL), spans 13.15 kilometres at an altitude of 11,578 feet, connecting strategic regions of Drass, Kargil, and Leh.
Officials highlight that the dual-end excavation approach—starting simultaneously from Baltal in Kashmir Valley and Minamarg in Ladakh—has accelerated progress despite the Himalayan terrain’s harsh climatic and geological challenges. With over 13 kilometres excavated, only a small section remains to connect the tunnel fully, signifying the final phase of construction before internal works begin.
Engineering Feat in the Himalayas
The tunnel employs the New Austrian Tunnelling Method (NATM), a flexible technique ideal for complex mountain terrains. This method allows adaptations based on ground conditions, ensuring both safety and efficiency. The tunnel will feature advanced ventilation systems, concrete lining, safety infrastructure, and a dedicated walkway for maintenance and emergency operations.
Harpal Singh, Joint Chief Operating Officer of MEIL, emphasized the importance of simultaneous excavation in maintaining timelines. Despite facing extreme challenges, including five avalanche incidents in five years, the project has achieved 10 million safe man-hours. A notable avalanche in January 2023 necessitated the rescue of 172 workers by the Army, reflecting the project’s risk and complexity.
Strategic and Economic Impact
Strategically located 24 kilometres from Sonamarg and 103 kilometres from Srinagar, the tunnel will revolutionize connectivity in the region. It will provide year-round access for civilians, ensure uninterrupted supply chains, and strengthen military logistics. Frequent closures of the Zojila Pass due to snow and avalanches have historically isolated these regions, making the tunnel a vital infrastructure project.
Economically, the tunnel is expected to boost tourism, trade, and employment, with over 1,200 personnel involved in its construction, 80 per cent of whom are locals. The project not only represents an engineering marvel but also a socio-economic catalyst for communities in the Himalayas.
Milestone Towards Completion
As Zojila Tunnel nears its breakthrough, the project transitions into final internal works, paving the way for operational readiness. Once complete, it will stand as a symbol of resilience, connectivity, and progress in one of India’s most strategically significant regions. The tunnel underscores the government’s commitment to modernizing infrastructure in difficult terrains, enhancing both regional development and national security.
The ceremonial breakthrough marks not just an engineering achievement but a step towards ensuring reliable, all-weather mobility, bringing strategic, economic, and social benefits to the northernmost regions of India.
