He said that besides offering the Armed Forces a strategic advantage by providing an alternate link to the critical Ladakh Sector, the tunnel has also been a boon for Lahaul & Spiti District residents in Himachal Pradesh.
The region has seen an unprecedented increase in the arrival of tourists. In a little more than a year, the valley and the state have witnessed exponential growth in the socio-economic domains and the Atal Tunnel is destined to play a defining role in the future development of the region.
The tunnel, built by using the New Austrian Tunneling Method (NATM), was dedicated to the Nation by Prime Minister Narendra Modi on October 03, 2020. It has been equipped with a semi-transverse ventilation system, where large fans separately circulate air throughout the tunnel.

An emergency tunnel has been integrated into the tunnel cross-section beneath the main carriageway for evacuation during emergencies. Fires inside the tunnel will be controlled within an area of 200 metres, and fire hydrants are provided at specific locations throughout the tunnel.
Pollution sensors continuously monitor the air quality in the tunnel. If the air quality in the tunnel is below the desired level, fresh air is injected into the tunnel via two heavy-duty fans on each side of the tunnel.
