India’s Atal Tunnel is now the World’s Longest Highway Tunnel above 10,000 ft!

The Atal Tunnel, officially known as the Atal Tunnel, is a remarkable engineering marvel located in the Indian state of Himachal Pradesh. Here is comprehensive information about the Atal Tunnel:

1. **Location**: The Atal Tunnel is situated in the Pir Panjal range of the Himalayas, near the town of Manali in Himachal Pradesh, India. It connects Manali to the Lahaul and Spiti Valleys, providing year-round accessibility.

2. **Length**: The tunnel is approximately 9.02 kilometers (5.6 miles) long, making it one of the longest road tunnels in India.

3. **Altitude**: It is also one of the highest road tunnels globally, with an altitude of about 3,100 meters (10,171 feet) above sea level.

4. **Purpose**: The tunnel was built to provide all-weather connectivity to the Lahaul and Spiti Valleys, which were previously cut off from the rest of the country during the winter months due to heavy snowfall, avalanches, and landslides.

5. **Construction**: The tunnel's construction began in 2010, and it was inaugurated on October 3, 2020, by Prime Minister Narendra Modi. It was initially named the Rohtang Tunnel but was later renamed the Atal Tunnel in honor of Atal Bihari Vajpayee, the former Prime Minister of India, who played a key role in its inception.

6. **Benefits**: The Atal Tunnel has several significant benefits, including reducing the travel distance between Manali and Keylong by about 46 kilometers and cutting travel time by several hours. It also ensures uninterrupted access to the region for both civilian and military purposes.

7. **Engineering Feat**: The tunnel's construction involved cutting through a mountain range, and it is equipped with state-of-the-art technology, including ventilation systems, emergency exit tunnels, and a fire-fighting system. It has made the region more accessible and safer for travelers.

8. **Tourism**: The tunnel has also boosted tourism in the region, as it allows tourists to visit Lahaul and Spiti Valley even during the harsh winter months, offering breathtaking views of the Himalayas.

9. **Economic Impact**: It has had a positive economic impact on the region by facilitating the movement of goods and people, leading to increased trade and commerce.

The Atal Tunnel is a significant infrastructure project in India and a testament to the engineering prowess of the country. It has not only improved connectivity but also opened up new opportunities for the development of the region.
