Comprehensive Safety Measures: NHAI collaborates with experts for Tunnel Audits and design reviews.

To ensure safety and adherence to the highest quality standards during construction, NHAI will undertake safety audit of all 29 under construction tunnels across the country. NHAI officials along with a team of experts from Delhi Metro Rail Corporation (DMRC) as well as other tunnel experts will inspect the ongoing tunnel projects and will submit a report within seven days. With a total length of around 79 km, the 29 under-construction tunnels are spread over different locations across the country with 12 tunnels in Himachal Pradesh, 06 in Jammu and Kashmir, 02 each in Maharashtra, Odisha, Rajasthan and one each in the states of Madhya Pradesh, Karnataka, Chhattisgarh, Uttarakhand and Delhi respectively.

NHAI also signed a Memorandum of Understanding with Konkan Railway Corporation Limited (KRCL). Under this agreement, KRCL will provide services for NHAI projects to review design, drawing and safety aspects related to tunnel construction and slope stabilization. KRCL will also conduct safety audits of tunnels and if required, suggest remedial measures. In addition to this, KRCL will organize training programs for capacity building of NHAI officials. This agreement will remain in effect for a period of two years.

Earlier in September 2023, NHAI signed a similar agreement with DMRC, who will provide services for reviewing planning, designing, construction and maintenance of tunnels, bridges and other structures on National Highways across the country.

“In a strategic move, NHAI solidifies partnerships with DMRC, reinforcing commitment to a secure and efficient National Highway network. The collaboration focuses on meticulous planning, design review, and maintenance of crucial infrastructures, showcasing NHAI’s dedication to national development.”
