In response to concerns raised regarding the absence of a separate escape tunnel in the under-construction Silkyara tunnel in Uttarkashi, the Indian government has provided clarifications on the safety measures in place.

Escape Route Provision

Union Road Transport and Highways Minister Nitin Gadkari stated that the Silkyara bi-directional tunnel on the Dharasu-Yumunotri highway NH-134 is equipped with a separation wall at the center of the carriageway. This separation wall serves as a safety measure, providing egress openings at regular intervals for vehicular crossover and pedestrian cross passage during emergencies.

Rescue Route Inquiry

In response to questions about the absence of a dedicated rescue route, Gadkari clarified that the tunnel is being constructed by Navayuga Engineering Company Ltd (NECL) through the National Highways and Infrastructure Development Corporation Ltd (NHIDCL). The design responsibility lies with the EPC contractor, and the tunnel is being built under the Engineering, Procurement, and Construction (EPC) mode.

Safety Reviews and Construction Challenges

Gadkari mentioned that following minor spalls and debris-forming cavities encountered during construction in 2019, the construction sequences and primary support systems have been regularly reviewed based on actual ground behavior. These reviews are approved by the authority's engineer engaged in the project and executed under the supervision of NHIDCL officials.

Char Dham Maha Marg Vikas Pariyojana

The minister also addressed concerns about the Char Dham Maha Marg Vikas Pariyojana, a 900-km project aimed at improving connectivity to the four holy towns. Gadkari clarified that the project was approved without an environmental impact assessment as each project is independent, with distinct start and end points. The projects are less than 100 km in length, and as per the Ministry of Environment, Forest, and Climate Change (MoEFCC) notification, projects exceeding 100 km require prior environmental clearances.

The government's clarifications on the Silkyara tunnel's safety measures and the Char Dham Maha Marg Vikas Pariyojana aim to address concerns raised by the public and ensure the safety of travelers and workers involved in these infrastructure projects.
