Why the Rohtang Pass Tunnel Is Important for India
The Atal Tunnel is one of India’s most remarkable infrastructure achievements, built to provide all-weather connectivity to the remote regions of Himachal Pradesh. Located in the Pir Panjal range of the Himalayas, the tunnel connects Manali to the Lahaul-Spiti valley. It is named after former Prime Minister Atal Bihari Vajpayee and plays a crucial role in improving connectivity, boosting tourism, and strengthening national security. The tunnel significantly reduces travel time and ensures year-round access to areas that were earlier cut off during heavy snowfall.
Overview of Atal Tunnel
The Atal Tunnel is a highway tunnel built under the Rohtang Pass in Himachal Pradesh. It is one of the longest highway tunnels in the world above 10,000 feet. The tunnel has transformed transportation in the region by providing safe and uninterrupted access even during extreme winter conditions.
Key Facts About Atal Tunnel
