The Atal Tunnel, also known as the Rohtang Tunnel, is a remarkable engineering marvel located in the Indian state of Himachal Pradesh near the town of Manali. Named after former Prime Minister of India, Atal Bihari Vajpayee, the tunnel is situated at an altitude of approximately 3,100 meters (10,171 feet) above sea level and is one of the highest road tunnels in the world.
Here's some key information about the Atal Tunnel:
Location: The Atal Tunnel is located beneath the Rohtang Pass in the Pir Panjal range of the Himalayas. It connects the Manali Valley to the Lahaul and Spiti Valley, providing all-weather connectivity to the remote regions of Himachal Pradesh.
Length and Construction: The tunnel stretches for approximately 9.02 kilometers (5.6 miles) and was constructed at a cost of around 3,200 crores (approximately 450 million USD). It is a horseshoe-shaped, single-tube tunnel with a two-lane roadway. Construction of the tunnel began in 2010, and it was inaugurated by Prime Minister Narendra Modi in October 2020.
Importance: Prior to the construction of the Atal Tunnel, the Rohtang Pass was the only link between the Manali Valley and the Lahaul and Spiti Valley. However, due to heavy snowfall and adverse weather conditions, the pass would often remain closed for several months during the winter, cutting off the region from the rest of the country. The tunnel provides round-the-year connectivity, reducing travel time and enhancing accessibility for locals as well as tourists.
Engineering Feats: The construction of the Atal Tunnel involved overcoming numerous engineering challenges, including the excavation of hard rock, negotiating high-altitude conditions, and ensuring safety and stability in a seismic zone. The tunnel is equipped with state-of-the-art technology for ventilation, lighting, and surveillance to ensure safe passage for vehicles.
Tourism and Economic Impact: The Atal Tunnel has not only facilitated easier access for locals and businesses in the region but has also opened up new opportunities for tourism. Visitors can now travel to the Lahaul and Spiti Valley throughout the year, contributing to the local economy and promoting cultural exchange.
Overall, the Atal Tunnel is a symbol of India's engineering prowess and a testament to the country's commitment to infrastructure development in remote and challenging terrains. It has significantly improved connectivity and socio-economic development in the region while also attracting visitors from around the world to marvel at its ingenuity and scenic beauty.
