Zojila tunnel breakthrough: Why digging through the Himalayas is an engineering challenge
The Zojila Tunnel, a 13-km passage through the Himalayas at 11,500 feet, is a major milestone for India's infrastructure projects. Tunnelling in the Himalayas is challenging due to high altitude, extreme temperatures, and unpredictable rock formations. Engineers used the New Austrian Tunneling Method to safely excavate the tunnel, implementing multiple safety systems and rescue plans.
