Prime Minister Shri @narendramodi will dedicate the Atal Tunnel to the nation and address public meetings in Himachal Pradesh on 3 October 2020.
Atal Tunnel, Rohtang (previously known as Rohtang Tunnel), named after former Indian Prime Minister Atal Bihari Vajpayee, is a highway tunnel built under the Rohtang Pass in the eastern Pir Panjal range of the Himalayas on the Leh-Manali Highway. At 9.02 km (5.6 mi) length, the tunnel will be one of the longest road tunnels in India and is expected to reduce the distance between Manali and Leh by 46 km (28.6 mi). 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).
The Leh–Manali Highway, one of the two routes to Ladakh, The Rohtang Pass receives heavy snowfall and blizzards during winter months and is open for road traffic for only four months in a year. The tunnel will keep the highway open during the winter. The other route to Leh is through the Zoji La on the Srinagar-Drass-Kargil-Leh highway, which also gets blocked by snow for nearly four months in a year. Construction of a 14 km long tunnel under Zoji La has been planned. These two routes are vital to feed military supplies into military sub-sector in the west facing Aksai Chin and the Siachen Glacier.
The Atal Tunnel is not exactly under Rohtang pass; it is slightly west of the pass. The south entrance is north of Dhundi on the other side of the Beas River. The northern end of the tunnel meets the existing Leh–Manali Highway near Teling village, west of Gramphu, which is the first village after Rohtang Pass on the existing highway.
