The tunnel reduced the distance between Manali and Leh by 46 km (28.6 mi) and reduced the travel time by 4 to 5 hours without any threat of road blockade or avalanche.[5][6]
The usefulness of the tunnel may be better illustrated thus: The 117 km distance from Manali to the south of the pass to Keylong on the north side of Rohtang Pass via Gramphu is usually covered by vehicles in about five to six hours, without counting the long hours of traffic jams on the hilly route. The same journey is much easier now as Manali to the South Portal of the tunnel is 24.4 kms ~ 50 mins, through the tunnel in approximately 15 mins and without traffic snarls, and North Portal to Keylong is 37 kms ~ 60 mins.
The tunnel is at an elevation of 3,100 metres (10,171 ft) whereas the Rohtang Pass is at an elevation of 3,978 metres (13,051 ft).
It was inaugurated by Prime Minister Narendra Modi on 3 October 2020.The Approximate cost of this project is ₹3200 crore(US$438 million)
