Rescue teams may reach the 41 workers stuck inside an Uttarakhand tunnel for over 170 hours in the next two days if the auger machine drilling into the debris block works properly, Union Minister for Road Transport and Highways Nitin Gadkari said today. Mr Gadkari and Chief Minister Pushkar Singh Dhami today visited the site of the tunnel collapse that has left 41 lives hanging by the thread. A part of the under-construction tunnel to connect Uttarkashi and Yamunotri collapsed last Sunday after a landslide, trapping the workers. This tunnel is part of the centre's ambitious Char Dham project.
