World’s longest highway tunnel
World’s longest highway tunnel: The building of the 9.2-km Atal Tunnel that connects Manali with Leh, the world’s longest highway tunnel above 10,000 feet, has been accomplished in a span of 10 years whereas the unique estimated time was lower than six years.
“Atal Tunnel, connecting Manali to Leh, is the world’s longest highway tunnel above 10,000 feet. The estimated period for completion of this tunnel was less than six years but it was completed in 10 years,” chief engineer KP Purushothaman stated.
“There are CCTV cameras at every 60 metres and emergency exit tunnels at every 500 metres inside the tunnel. The tunnel will reduce the distance between Manali and Leh by 46km and four hours can be saved,” he stated.
Fire hydrants have additionally been put in contained in the tunnel in case of any hearth incident.
“The induction and de-induction of resources was a difficult task while it was under construction. We did face a lot of challenges but together we were able to complete its construction. The tunnel is 10.5 metres wide, including a 1-metre footpath on both sides,” he stated.
Atal Tunnel mission director Colonel Parikshit Mehra stated that many specialists working throughout the group had been of the opinion that the alignment of the tunnel must be modified.
“We have had this dream to connect Leh and this was the first step to the connectivity ladder. This tunnel was a challenging project because we were working from two ends. The other end was in North, across the Rohtang Pass which was accessible only for five months in a year,” he stated.
