  • 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.
