Union Road Transport and Highways Minister Nitin Gadkari on Tuesday, June 9, 2026, celebrated the historic breakthrough of the Zojila Main Tunnel, calling it a symbol of India's technological prowess, engineering capability, and indomitable resolve. The minister posted a video on X marking what he described as a landmark moment for the 14.15-km bi-directional tunnel on National Highway-1, which will provide all-weather connectivity between Srinagar and Leh.

Context

Gadkari's post hailed the Zojila breakthrough as 'एशिया की सबसे लंबी सुरंग' ('Asia's longest tunnel') and a testament to India's engineering ambition. A tunnel breakthrough — the moment the boring machine pierces through the final rock face connecting two ends — is a critical civil-engineering milestone, signalling that the tunnel's excavation is complete and finishing work can begin. The minister used hashtags #ZojilaTunnel, #AllWeatherRoad, and #GatiShakti, anchoring the achievement within the government's flagship infrastructure narrative.

Policy Backdrop

The Zojila Tunnel project received Cabinet approval in 2018 at an estimated cost exceeding Rs 6,800 crore, with the foundation stone laid by Prime Minister Narendra Modi in May 2018. The project was incorporated under the Bharatmala Pariyojana, a national programme for developing economic corridors and border roads. It is also aligned with the PM Gati Shakti national master plan, launched in 2021, which integrates infrastructure development across ministries to enable seamless multimodal connectivity. The tunnel employs the New Austrian Tunnelling Method to navigate the challenging geology beneath the Zojila Pass, one of the world's most treacherous high-altitude mountain passes.

The Zojila Pass, situated at an altitude of over 11,500 feet, remains snowbound for roughly six months each year, effectively cutting off Ladakh from the Kashmir Valley and the rest of India during winter. The tunnel is designed to eliminate this seasonal isolation, keeping the Srinagar–Leh highway open through the harshest winters.

Stakeholders and Impact

The tunnel's completion will directly benefit Ladakh's approximately 2.74 lakh residents who face months of supply-chain disruption every winter. Defence logistics to forward areas along the Line of Actual Control (LAC) will also be significantly enhanced, as the Border Roads Organisation (BRO) and the armed forces have long depended on this corridor for the movement of troops and materiel. Traders, tourists, and the broader economy of the Union Territory of Ladakh stand to gain from year-round road access, lower freight costs, and reduced travel times on the Srinagar–Leh route.

The project forms part of a broader Himalayan connectivity push that includes parallel initiatives such as the Shinku La Tunnel, aimed at opening an alternate all-weather route to Ladakh via Himachal Pradesh. Together, these projects represent a sustained strategic and developmental commitment to India's northernmost frontier.

What's Next

With the breakthrough achieved, attention now shifts to the remaining civil, electrical, and safety fitout work inside the tunnel before it can be declared open to traffic. Full operationalisation will require completion of ventilation systems, emergency lay-bys, fire-suppression infrastructure, and the approach roads on both the Srinagar and Leh sides. Once operational, the tunnel is expected to cut the current Srinagar–Leh travel time substantially and transform logistics across the region, reinforcing India's strategic posture along its northern borders.
