Fotu La Tunnel Project Approved in Ladakh

The Fotu La Tunnel project on National Highway-01 in Ladakh has been approved with an estimated cost of ₹1,196.22 crore. The project covers a 2.65-kilometre alignment and includes a 1.96-kilometre twin-tube tunnel and 0.69 kilometre of approach roads.

Fotu La Pass and NH-01

Fotu La Pass is located at an altitude of about 4,108 metres and is the highest point on the Uri–Srinagar–Leh highway corridor. National Highway-01 is a key road link in Ladakh for civilian movement, essential supplies, and defence logistics.

Tunnel Design and Route Features

The project includes a unidirectional twin-tube tunnel at Fotu La and approach roads on both sides. A twin-tube tunnel has two separate tubes for traffic movement, and unidirectional traffic flow is used in road tunnels to improve operational control and safety.

Road Conditions in High-Altitude Ladakh

The existing road at Fotu La has steep gradients, sharp hairpin bends, and winter closures caused by snowfall and icy conditions. High-altitude roads in Ladakh often face weather-related disruption because of low temperatures, snow accumulation, and difficult terrain.

Important Facts for Exams

• Fotu La Pass is one of the high-altitude passes on the Srinagar–Leh road axis in Ladakh.
• National Highway-01 connects Uri, Srinagar, and Leh in the Union Territory of Ladakh.
• A twin-tube tunnel usually carries traffic through two parallel tubes for separate movement directions.
• Road tunnels in snow-bound regions are used to reduce weather-related disruption and improve year-round connectivity.

Strategic and Transport Context

The tunnel is expected to reduce the travel distance by about 8.5 kilometres after completion. Ladakh’s road infrastructure has strategic value because it supports both civilian transport and defence movement in a border region.
