In India’s infrastructure development growth, tunnels are central to how the country builds roads, railways, metros, and even water systems. At times, when cities are choking, land is scarce, and geographical obstacles block connectivity, tunnels ensure smooth mobility and connectivity.
In such a scenario, building underground tunnels is a reliable decision.
In fact, initiatives associated with the Bharatmala project, road expansion, and strategic border infrastructure development are significantly increasing the tunnel projects every quarter.
This blog provides detailed insights into the tunnel landscape of India, including tunnel types, relevant authorities, commonly used technologies, active tenders, and much more.
What Are The Tunnel Project Tenders Increasing Across India?
The surge in tunnel project tenders across India is driven by various factors.
First, there is no land available for acquisition in cities like Mumbai and Delhi. Due to this, land cost alone can kill the projects. This means surface expansion is almost impossible without massive disruption. So, the government is now implementing the metro projects below ground.
In addition, some of the leading government schemes and initiatives need tunnels to ensure constant connectivity.
Another benefit that is driving the surge in tunnel project tenders is reduced travel time. A tunnel can greatly cut the travel time from hours to minutes.
As the country has mighty Himalayas in the north and the Western Ghats in the south, building around them is slow and resource-consuming. But building through them is easy.
Apart from these, the tunneling technology has become more advanced and safer to use. Execution risks have reduced, increasing confidence in tunnel development.
Where Are the Major Tunnel Project Tenders Emerging in India in 2026?
In India, a huge majority of the tunnel project tenders are emerging from the following states:
- Maharashtra
- Jammu & Kashmir
- The Northeast States
- Uttarakhand
For instance,
In Maharashtra, a huge number of tunnel projects are in progress. Most of the tenders are issued for
- Mumbai–Ahmedabad Bullet Train Tunnel
- Thane–Borivali Twin Tunnel Project
- Mumbai Underground Metro & Gateway Corridor tunnels
- Goregaon–Mulund Link Road Tunnel
In states like J & K and Ladakh, the government is prioritizing border infrastructure. Hence, tunnel project tenders are expected to increase in the state. Various activities and tenders associated with the Zoji La Tunnel, Z-Morph Tunnel, USBRL railway tunnels, and many more are in progress.
In Northeast India, the government is working on various projects, such as the Brahmaputra Underwater Tunnel, the Dimapur–Kohima Railway Line Tunnel, and various other planned tunnels in the LAC regions.
In Uttarakhand, several tunnel project tenders are open for works related to the Rishikesh-Karnaprayag Railway line, Silkyara-Barkot Tunnel, Rudraprayag Tunnel Project, etc. Besides these, various other tunnels are in progress across the state.

Who Are the Key Authorities Issuing Government Tunnel Projects in India?
In India, various authorities issue government tunnel projects, each responsible for different types of tunnel construction tenders. Here are the major ones.
- National Highways Authority of India
- National Highways & Infrastructure Development Corporation Limited
- IRCON International
- Rail Vikas Nigam Limited
- Delhi Metro Rail Corporation
- Mumbai Metro Rail Corporation
- State Metro SPVs
- Border Roads Organisation
- State Public Works Departments
- National High-Speed Rail Corporation Limited
- Urban Development Authorities
Businesses should stop reacting and start predicting where the next tunnel project tender will come from through Tender Grid. The platform aggregates the different tunnel tenders from the official eProcurement portals of the above-mentioned authorities in a centralized place.
Different Types of Tunnel Project Tenders
There are several types of tunnel construction tenders available for contractors in India, each differing in scope, technology, contract structure, and qualification requirements. The following are the leading ones:
1. Highway Tunnel Construction
These tenders deal with the projects related to tunnel excavation, twin-tube construction, ventilation, lighting, fire safety systems, and various other works.
2. Metro Rail Tunnel
Such tenders focus on the development of underground metro rail transit systems in urban areas. Projects associated with TBM-driven tunnel excavation, underground station box construction, cross-passages, ventilation shafts, signaling, etc., are executed through these.
3. Railway Tunnel Construction
These types of tenders are issued to construct tunnels for passenger and freight rail networks. Tunnel excavation and lining, track alignment, ballast work, drainage and safety systems, electrification provisions, and various other projects are completed through these tenders.
4. Hydropower Tunnel
Such tunnel tenders cover the development of underground water channels used for electricity generation, including headrace and tailrace tunnels. Various types of works, such as headrace tunnel excavation, tailrace tunnel construction, pressure/surge shafts, underground powerhouse caverns, etc., are carried out under these tenders.
5. Irrigation/Water Supply Tunnel

Conclusion
In 2026 and beyond, tunneling is one of the major focuses of India’s sovereign and urban strategy. Earlier, tunneling projects were limited in number. Today, due to land scarcity, difficult terrains, and densely populated cities, they are everywhere. In such a scenario, tunnel project tenders are no longer occasional opportunities: rather, they are becoming a steady pipeline.
Whether it’s metro rail tunnel tenders in crowded cities, high-risk government tunnel projects in border regions, or expansion of the metro across Tier 1 and Tier 2 cities, the bar is higher than ever. Businesses should consider using Tender Grid to find the latest tunnel-related tenders effortlessly. It also greatly elevates the chances of winning.
