“We are confident of achieving the critical breakthrough between April and May next year,” Singh said.

Despite harsh winter conditions, engineers and workers continue construction work with determination. Winter temperatures at the site often plunge to minus 18 degrees Celsius at night, while daytime temperatures remain below freezing. The region is also prone to avalanches, making construction during winter months particularly challenging.

“The challenges are many, complex geology, water ingress and extreme cold, but our focus is on zero risk and maximum safety,” Singh said.

“With the pace of work and the systems in place, we are confident of meeting our targets. We are confident that by May 2026, the tunnel will be fully connected from both sides. After the breakthrough, work will accelerate on eight to 10 additional fronts focusing on finishing, lining and safety installations,” Singh said.

“If no major unforeseen problems arise, the tunnel is expected to be completed between May and September 2028.”

The project was awarded to MEIL in October 2020 and work began in April 2021.

At present, around 1,200 engineers, technicians, mechanics and labourers are engaged in the project.

“To support them during the severe winter months, extensive arrangements have been put in place. Labour camps are equipped with round-the-clock electricity, hot water and heating facilities. Heated cabins have been installed near work sites to provide shelter to workers during operations, and all machinery is fitted with electronic heaters for the warmth of workers to ensure efficient functioning in sub-zero temperatures,” Singh said.
