Rohtang Pass, the crucial high altitude road link between Manali and Keylong in Himachal Pradesh, has been shut for traffic due to heavy snowfall. The pass normally opens to traffic in May. In the past two days, the Rohtang Pass experienced more than five-feet snowfall. The GREF (General Reserve Engineering Force), a wing of the Border Roads Organisation (BRO) that maintains the pass, has withdrawn its men and machinery.The Rohtang Pass, at 13,050 feet above sea level, is strategically vital to maintain supplies to the military posted in Jammu and Kashmir’s ladakh region along the borders with China and Pakistan.
