India has inaugurated its longest precast cut-and-cover tunnel, a 920-metre structure located at an altitude of 12,300 ft (3,750 m) in a sensitive border region. The project was formally opened on 7 December 2025 by Defence Minister Rajnath Singh. The tunnel is designed to improve troop movement, strengthen supply lines and bolster operational readiness in challenging high-altitude terrain.

The company has expressed gratitude to the Ministry of Defence and the Border Roads Organisation for their support and guidance, noting that it is honoured to contribute to a project of such strategic significance and remains committed to delivering infrastructure that strengthens India’s defence capabilities.
