Therefore, the government is stressing on setting up a ropeway between Kothi village which is in Manali and Rohtang Pass. The NGT (National Green Tribunal) has asked the state government of Himachal Pradesh to complete all the formalities to start a ropeway. With the coming of a ropeway, we can reduce carbon emission from vehicles. Heavy snowfall blocks the road in winter and a ropeway will be very useful. Road tunnel under the Pass As the pass gets blocked by snow and the road over the pass closes from November to May rendering Lahaul and Spiti districts north of the pass inaccessible, a need was felt to build a tunnel under the pass. The project was announced by the then Prime Minister Atal Bihari Vajpayee on 3 June 2000. The work was started by BRO on 6 May 2002. The foundation stone of the project was laid on 28 June 2010 by Sonia Gandhi in her capacity as the Chairperson of National Advisory Council. The road tunnel called Atal Tunnel has been excavated and became operational on 3 October 2020 after formal inauguration by Prime Minister Narendra Modi. It obviates the need to travel over the Rohtang Pass. While it takes 4 to 6 hours to ascend, negotiate and descend the Rohtang Pass, travel through the Rohtang Tunnel takes only about 30 minutes.
