Atal Tunnel has been certified by the World Book of Records, as the 'World's Longest Highway Tunnel above 10,000 Feet', during a landmark ceremony.

Nestled in the beautiful ranges of the mighty Himalayan ranges, the Atal Tunnel is a major milestone in India’s infrastructure development. This tunnel, also known as the Rohtang Tunnel, is a state-of-the-art engineering marvel that connects the remote regions of Himachal Pradesh to the rest of the country.

The tunnel is named after former Prime Minister of India, Shri Atal Bihari Vajpayee and is dedicated to his memory. The tunnel is strategically located and acts as an essential link between the Lahaul and Spiti valleys, which were previously only accessible via the Rohtang Pass and often closed during winter due to heavy snowfall.
