The Zojila Tunnel on the Srinagar-Leh Highway achieved its final breakthrough in June 2024 [3], marking a major milestone for the project.
This engineering feat is critical because it establishes all-weather connectivity between the Kashmir Valley and Ladakh. Previously, the Zojila Pass was subject to seasonal closures due to heavy snowfall, which isolated the region for several months each year.
Measuring 13.15 kilometres [1], the project is described as the world's longest single-tube bi-directional road tunnel at high altitude [2]. The tunnel passes under the Zojila Pass in the Himalayas, removing the reliance on a treacherous mountain road that often trapped travelers during winter months.
Lieutenant Governor Manoj Sinha, representing the project, said the tunnel will ensure year-round connectivity. He said the infrastructure will boost tourism and strengthen security measures between Jammu & Kashmir and Ladakh.
Engineering agencies worked to complete the tunnel to reduce travel time and provide a reliable route for the movement of essential goods. The breakthrough in June 2024 [3] signals that the project is now nearing final completion.
By bypassing the high-altitude pass, the Indian government aims to maintain a permanent link for both civilian and military transport. The tunnel's design allows for two-way traffic within a single tube, which is a rare technical achievement for a project at this elevation.
“The Zojila Tunnel is the world's longest single-tube bi-directional road tunnel at high altitude.”
The completion of the Zojila Tunnel fundamentally changes the logistics of the region by eliminating the seasonal blockade of the Srinagar-Leh Highway. Beyond tourism, this provides the Indian military with a strategic advantage by ensuring the uninterrupted movement of troops and supplies to the Ladakh border regardless of weather conditions.
