New Delhi: The Union Cabinet chaired by Prime Minister Narendra Modi has decided to honour the contribution of former PM Atal Bihari Vajpayee by naming the Strategic Tunnel under Rohtang Pass after him on 25 December, which happens to be his birthday. The historic decision to construct a strategic tunnel below the Rohtang Pass was taken on 3 June 2000 when late Atal Bihari Vajpayee was the Prime Minister. The foundation stone for the Access Road to the South Portal of the tunnel was laid on 26 May 2002.
The 8.8 kilometre long tunnel is the world’s longest tunnel above an altitude of 3,000 metres. It will reduce the distance between Manali and Leh by 46 kilometres and save crores of rupees in transport costs. It is a 10.5 metre wide single tube bi-lane tunnel with a fire proof emergency egress tunnel built into the main tunnel itself.
The Border Roads Organisation (BRO) worked to overcome major geological, terrain and weather challenges that included the most difficult stretch of the 587-metre Seri Nalah Fault Zone during the tunnel’s construction. Breakthrough from both ends was achieved on 15 October 2017.
The tunnel is now nearing completion and is a step in the direction of providing all weather connectivity to remote border areas of Himachal Pradesh and Ladakh which otherwise remained cut off from the rest of the country for about six months during winters.
