The Prime Minister has inaugurated the Atal Tunnel in Himachal Pradesh’s Rohtang

The tunnel connects Solang Valley near Manali to Sissu in Lahaul and Spiti district.
The 9.02-km tunnel is the world’s longest highway tunnel in the world above the height of 3,000 meters.
It cuts through a mountain west of the Rohtang pass and will shorten the distance between Solang Valley and Sissu by around 46 km and will take around 15 minutes to cover. Earlier, it would take nearly 4 hours to travel between the two points.
All year Connectivity: The Atal tunnel is the first step towards all-year connectivity to Ladakh. The tunnel has the potential to link Ladakh to Manali and Chandigarh throughout the year, as it would bypass Rohtang Pass, which is snowed in through the winter months.
Strategic: The tunnel provides a strategic advantage to the country's armed forces by providing year-long connectivity to border areas. It will save an entire day for troops and supplies as they move towards forward posts.
