The Atal Tunnel has been built by Border Road Organisation at an altitude of 3000 metres. Which places are connected by this tunnel?

Correct Answer: Manali to Lahaul-Spiti

Explanation:

The Atal Tunnel (also known as the Rohtang Tunnel) is a highway tunnel built under the Rohtang Pass in the eastern Pir Panjal range of the Himalayas on the Leh-Manali Highway in Himachal Pradesh, India.

Key highlights of the Atal Tunnel:

1. Construction: It was built by the Border Roads Organisation (BRO) at an altitude of approximately 3,000 metres (10,000 feet) above mean sea level.

2. Connectivity: The tunnel connects Manali to Lahaul-Spiti valley, providing all-weather connectivity to the region which previously remained cut off for nearly six months every year due to heavy snowfall at Rohtang Pass.

3. Distance Reduction: It reduces the road distance between Manali and Keylong (in Lahaul-Spiti) by about 46 km and saves around 4 to 5 hours of travel time.
