Benefits of Atal Tunnel

• Because of heavy snow, the interconnecting path between Manali and Leh could not be used for almost 6 months of the year. This problem has been resolved by the construction of the Atal Tunnel. Now, using this tunnel, traveling will be possible throughout the year
• The biggest advantage of this tunnel is that it will help the armed forces to have easy connectivity to all the border areas around
• The transportation of troops and supplies will become more convenient for the Army Personnel
• The entire route of the tunnel will reduce the distance between Leh and Manali by 46 km and reduce the travel time by 4 hours
• Easy access to medication and basic necessities will be improved. People who had to earlier travel miles will now be able to get all commodities easily as transportation will become easy
• A lot of economic benefits are provided to Leh and Ladakh through tourism. Thus, the Atal Tunnel will also prove helpful for tourists traveling to these areas
• Another remarkable significance of the Atal Tunnel is that it will ensure that farmers are able to supply the vegetables and crops on time, without any effect on the quality of the crops

The significance of the Atal Tunnel can be observed in different fields and for different sectors of people. Thus, this will promote and improve the geographical and infrastructural growth of the Indian mountainous region.

History and Development of Atal Tunnel

Although inaugurated in 2020, the announcement and foundation for the tunnel were made almost two decades back.

• The initial announcement to create such a tunnel was made by Late Atal Bihari Vajpayee on June 3, 2000
• The responsibility to complete the construction was handed over to the Border Roads Organisation (BRO) in 2002
• But due to the increasing cost of the project, from Rs.400 crore to Rs.900 crore, the project had been brought to a standstill
• Later, in 2010, the UPA Chairperson, Sonia Gandhi, had laid the foundation of this project in Solang Valley, near Manali
• Gradually the digging up process began for the tunnel and only emergy services were allowed through the route
• By September 2020, the entire construction was complete, and finally, on October 3, 2020, the project was inaugurated

It took decades to complete the project but today, it has opened a better path for Armed forces, farmers, and tourism. And with exceptional safety features, it has given a new perspective to the Indian infrastructure and road safety.
