As the rescue teams race against time to save the trapped workers, Prime Minister Narendra Modi today spoke to Uttarakhand Chief Minister Pushkar Singh Dhami to take stock of the situation.
The new plan to create an alternative escape route involves drilling a vertical hole on the top of the hill under which the tunnel is located.
The report further claimed that the map shows such an escape route was also planned for the 4.5 km Silkyara tunnel, but it was never built.
Rescue operations continued for the third day to evacuate 40 workers still trapped inside an under-construction tunnel that collapsed on Sunday.
