Several workers are feared trapped inside a tunnel in Uttarakhand after a part of the under-construction structure collapsed today. Efforts are on to open the tunnel and rescue the trapped workers from the tunnel. The tunnel is meant to connect Silkyara to Dandalgaon in Uttarakhand's Uttarkashi. It is being built under the Char Dham Road Project and aims to reduce the journey from Uttarkashi to Yamunotri Dham by 26 kilometres.
