Chenani-Nashri tunnel is India's longest, and safest

A unique feature of the tunnel is that at every 150 metres it has an emergency SOS box and a safety evacuation passage connecting to a safety tunnel constructed parallel to the main tunnel. "The tunnel has an Incident Detection Systems under which if any accident happens, our control team will get to know before the victim contacts us through the SOS call box. Accordingly, our rescue team will help in evacuation of the person and vehicle through the safety tunnel," said Chandwar. He said the tunnel has hydrants at every 150 metres, to tackle any kind of fire incidents.
