The Atal Tunnel, located in the Himalayas in India, represents a remarkable milestone in modern engineering and is a portal to the beautiful regions of Lahaul and Ladakh. As the world’s longest highway tunnel above 10,000 feet, it has transformed connectivity, tourism, and economic development in incredibly remote regions.
Atal Tunnel Location and Its Geographical Importance
The Atal Tunnel, located in Himachal Pradesh, connects Manali directly to the Lahaul Valley, greatly reducing time of travel time. The tunnel avoids the dangerous Rohtang Pass and extends Himachal Pradesh to Ladakh, reducing each journey by 46 km and four to five hours. This important infrastructure adds to regional connectivity profoundly and contributes to social and economic development.
Atal Tunnel History and Background
The Atal Tunnel has had a vision since the early 2000s for enabling all-weather interconnectivity to the reachable parts of the Lahaul and Spiti valleys. Former Prime Minister Atal Bihari Vajpayee was an ardent initiate of this infrastructure project, laying the foundation stone in 2002. After many interventions and challenges, the project has successfully culminated in the example of urbanisation, and the project was inaugurated on the 3rd of October 2020.
Atal Tunnel Construction & Engineering Facts
The Atal Tunnel spans 9.02 kilometers and reaches an altitude of more than 10,000 feet. It is a single-tube, horseshoe-shaped tunnel with two lanes. The construction teams worked through some very tough challenges, such as inclement weather, landslides, and water infiltration into the tunnel to get to the project. The Border Roads Organisation (BRO) and other organizations used advanced technologies and some advanced materials as part of the construction to ensure the tunnel’s strength and integrity.
Atal Tunnel Features & Technical Facts
The Atal Tunnel has a width of 10 meters for an 8-meter-wide lane in the center and a footpath on either side that is one meter wide. A semi-transverse ventilation system is also in the tunnel to ensure fresh air will be supplied throughout the full length of the tunnel. The emergency tunnel is below the main tunnel and is 2.25 meters tall and 3.6 meters wide. Fire hydrants are placed at intervals along the tunnel. There is a public announcement system, CCTV cameras and pollution sensor systems are also in place to monitor traffic and air quality in the tunnel to ensure a safer overall system.
