India Orders Safety Audit of Tunnels After Collapse in Himalayas

NEW DELHI: The National Highways Authority of India (NHAI) will carry out a safety audit of more than two dozen tunnels it is building after one such tunnel in the Himalayas collapsed this month, trapping 41 construction workers, the government said on Wednesday (Nov 22).

Rescuers have been battling to pull out the 41 men stuck in a 4.5km tunnel in the mountainous Uttarakhand state since it caved in early on Nov 12. Authorities have not said what caused the collapse, but the region is prone to landslides, earthquakes and floods.

The construction spree has been questioned by some environmental experts who fear damage to the fragile Himalayan ecosystem and on grounds of safety.

“To ensure safety and adherence to the highest quality standards during construction, NHAI will undertake (a) safety audit of all 29 under-construction tunnels across the country,” the government said in a statement. The NHAI is a federal body which builds and manages a network of national highways.

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.


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 work on the Char Dham project, for land subsidence incidents in the region.

“The Char Dham project was planned in a hurried manner,” said Ravi Chopra, an environmentalist, alleging that necessary precautions were not taken in the area which is known for limestone rocks, which dissolve in water, weakening structures.

The federal government has said it employed environmentally friendly techniques in the design to make geologically unstable areas safer. Chopra, who headed a Supreme Court-appointed expert panel to study the impact of the project, had resigned from the committee, saying he was frustrated its recommendations were not implemented.

“The kind of geological investigation that should have been done was not done,” he told Reuters.
