India’s Longest Transport Tunnel in Rishikesh-Karnaprayag Rail Project

India has achieved a major milestone by completing its longest transport tunnel, part of the Rishikesh-Karnaprayag rail project in Uttarakhand. This engineering marvel stretches over 14.59 km and is constructed using advanced New Austrian Tunnelling Method (NATM). The tunnel is a key part of the 125-km railway project, designed to boost connectivity in the Himalayan region and promote tourism and pilgrimage. Once operational, the rail line will reduce travel time, enhance safety, and strengthen infrastructure in the Char Dham area. This achievement marks a significant step forward in India’s transportation and engineering capabilities – indiatoday.in
