NHAI officials along with others from the Delhi Metro Rail Corporation will inspect ongoing tunnel projects and submit a report in seven days, it added.
These would include 12 tunnels in the Himalayan state of Himachal Pradesh, six in the Jammu and Kashmir region, and the rest in other states including Uttarakhand.
CONTROVERSIAL PROJECT
The collapsed tunnel is located on the Char Dham pilgrimage route, one of the most ambitious projects of Prime Minister Narendra Modi’s government.
It aims to connect four important Hindu pilgrimage sites of North India through 890km of a two-lane road being built at a cost of US$1.5 billion.
Environmentalists and residents have blamed rapid construction, including the Char Dham project, for land subsidence incidents in the region.
