India has linked both ends of the Zojila tunnel, marking a historic breakthrough in the project's tunneling work [1, 2].
This development is critical because it establishes year-round road connectivity between Kashmir and Ladakh. Previously, the Zojila Pass remained closed during winter months, hindering the movement of civilians and military forces.
The breakthrough occurred on June 9, 2024 [3], at the eastern portal located at Minamarg in the Kargil district [1, 2]. The tunnel is situated under the Zojila Pass on the Srinagar-Kargil-Leh highway [2]. Union Minister Nitin Gadkari said the achievement is a major milestone for the region [4].
Reports on the exact length of the tunnel vary slightly. Some sources cite the length as 13.5 km [1], while others list it as 13.15 km [2]. Despite the variance, the project is recognized as the world's longest bi-directional tunnel [4] or the world's longest single-tube bi-directional bypass [2].
The project has been in development for approximately 13 years, having been announced around 2011 [3]. The construction aims to bypass the treacherous mountain pass, which is prone to landslides and heavy snowfall.
By ensuring all-weather access, the tunnel is expected to boost tourism to Ladakh and enhance strategic border access [2]. This connectivity allows for the faster movement of essential supplies and personnel regardless of the season, a necessity for national security in the border regions [2].
“The project will provide all-weather, year-round road connectivity between Kashmir and Ladakh.”
The Zojila tunnel removes a primary geographical barrier that historically isolated Ladakh for several months each year. Beyond the economic benefits of increased tourism, the project serves a critical strategic purpose by allowing the Indian military to mobilize troops and equipment to border regions without relying on seasonal weather windows.
