The government officials have mentioned that there are no specific Indian or international codes mandating the construction of an escape tunnel in the Silkyara tunnel at Uttarkashi. They argue that the single tube divided into two interconnected corridors by a partition wall can serve as an escape tunnel in case of an emergency, with "egress openings" every 500 meters. The expert committee, led by R K Dhiman, has concluded their visit to the site and will be submitting their final report soon. Additionally, the ministry of road transport and highways mentioned that the Indian Road Congress guidelines do not recommend emergency exits for tunnels longer than 1.5 km.
