Tunneling Expertise: Navigating Complexities

DMR undertakes some of the most complex tunneling projects across India, combining advanced equipment, expert teams, and time-tested techniques. Our focus is on safe, durable, and economically viable tunnel construction that meets the demands of modern infrastructure.

Safe & Efficient Tunneling

At DMR, safety is not a checkbox—it’s a core principle. We follow stringent safety standards at every phase of the tunneling process to protect our workforce and the environment. Our team leverages efficient excavation methods and modern material handling systems to reduce timelines and costs without compromising quality.

Urban Tunneling

Building tunnels in densely populated cities presents unique challenges. DMR excels in urban tunneling with minimal disruption to daily life and public services. Through detailed planning and innovative construction strategies, we ensure surrounding infrastructure and utilities remain safe and functional throughout the build.

Utility Tunnels

Utility tunnels are vital to urban sustainability. We design and construct underground corridors that securely house water pipelines, power lines, sewage systems, and telecom infrastructure—ensuring ease of maintenance and uninterrupted service for years to come.

Tunnel Development

Tunnel construction is not just about carving through mountains or going underground—it's about unlocking access, enabling connectivity, and overcoming geographical barriers that once limited development. Tunnels play a critical role in enhancing transport efficiency, reducing travel time, and ensuring year-round connectivity in challenging terrains such as hilly regions and urban centers. They facilitate seamless movement for both passengers and goods, particularly in regions where conventional infrastructure is not feasible. According to the Ministry of Road Transport and Highways, tunnel infrastructure is a key focus in expanding India's all-weather connectivity and strategic mobility. At DMR, we take pride in driving this transformation forward by building safe, durable, and technologically advanced tunnels that empower communities, support economic growth, and strengthen national integration.

Tunneling in India: Key Statistics

India has over 250 operational tunnels across road, rail, and hydropower sectors.
The Chenani-Nashri Tunnel (now Dr. Syama Prasad Mookerjee Tunnel) is India’s longest road tunnel at 9.28 km.
The Pir Panjal Railway Tunnel, at 11.2 km, is one of the longest railway tunnels in India.
Tunnel construction has grown over 200% in the past decade, driven by increased urbanization and strategic connectivity goals.
The Atal Tunnel, located in Himachal Pradesh, is India’s longest road tunnel at 9.02 km, improving connectivity between Manali and Leh.
The Eastern Peripheral Expressway features multiple tunnels to alleviate traffic congestion around Delhi, contributing to the region's infrastructure development.
The ongoing Char Dham Highway Project includes the construction of several tunnels, including the 4.6 km long Sela Pass Tunnel, aimed at enhancing road accessibility to the Himalayan shrines.
Highway tunnels play a crucial role in mitigating landslides and ensuring year-round road connectivity in regions like Jammu & Kashmir and Himachal Pradesh, where mountainous terrain poses challenges.
