Every year, throughout July to September, the road gets to be a passage to the men and women of Lahul valley transporting their funds crop, potatoes and peas to the marketplaces across Atal Tunnel to Kullu and earning income for the unstable temperature interval of nine months.

Identified as one of the highest trafficable passes in the world, the Rohtang go is designed to produce an all-climate route to Leh and Lahaul and Spiti valleys in Himachal Pradesh. The Rohtang Move Highway Tunnel is positioned in the Western Himalaya location of Northern India with its altitude of 3,980 m.
