India’s First 8-Lane Tunnel on Delhi-Mumbai Expressway Complete Under Mukundara Tiger Reserve: Full Update March 2026
If you’re curious about the latest progress on the Delhi-Mumbai Expressway, this blog covers everything you need to know. From operational stretches and travel time reduction to the newly completed 8-lane Kota Tunnel beneath the Mukundara Tiger Reserve, we explain how this mega-project will transform travel across Haryana, Rajasthan, Madhya Pradesh, and Gujarat. This Delhi-Mumbai Expressway tunnel update helps you understand the full benefits, upcoming milestones, and how it will impact commuters and wildlife alike.
Operational Status: Major Stretches Already Functional
As of March 17, 2026, the 1,380 km Delhi-Mumbai Expressway is largely operational from Delhi to Vadodara. Traffic is moving smoothly through Haryana and Rajasthan, with vehicles traveling at speeds up to 120 km/h.
Officials report that daily traffic ranges from 25,000-30,000 vehicles, and this number is expected to rise after the tunnel is fully operational. The median is 21 meters wide, allowing future lane expansion if required. Amenities like rest areas, food courts, and parking are also being developed along the corridor.
Landmark Achievement: 8-Lane Kota Tunnel Completed
A major milestone in this Delhi-Mumbai Expressway tunnel update is the completion of the 4.9 km Kota Tunnel in Rajasthan. This tunnel, the country’s first 8-lane underground tunnel, passes beneath the Mukundara Hills Tiger Reserve to protect wildlife.
The tunnel has two tubes, each with four lanes, totaling eight lanes. Special precautions during construction ensured minimal disturbance to animals. Above the tunnel, a natural forest area remains intact so that wildlife won’t even notice the highway passing below.
Trial runs for the tunnel are expected to begin soon, with final inspections underway. Once fully operational, it will significantly reduce travel time from Gurugram to Vadodara from 20-22 hours to just 10-12 hours.
Final Stretches: Gujarat Sections Face Minor Delays
While most of the expressway is functional, some sections in Gujarat (Vadodara-Mumbai) have faced delays. Officials initially targeted March 2026 for full completion, but final stretches may now be operational by late 2026 or early 2027-28.
Once fully connected to Mumbai’s JNPT port, the Delhi-Mumbai Expressway tunnel update promises to cut the total Gurugram-Mumbai journey from 24 hours to just 12 hours, saving time and fuel for both personal and commercial travelers.
Travel Time & Connectivity Gains
The Delhi-Mumbai Expressway tunnel update is not just about speed—it’s about connectivity. New projects approved along the corridor will link cities like Ujjain directly to the expressway, boosting regional development.
Tourist destinations such as Ranthambore, Mukundra, and other forest areas will become more accessible without disturbing the environment. Commuters will experience smoother travel with enhanced safety, while the surrounding ecosystem remains protected thanks to innovative engineering.
Economic & Regional Impact
This expressway is expected to accelerate economic development in Haryana, Rajasthan, Madhya Pradesh, and Gujarat. Faster logistics and better connectivity will support industries, tourism, and local businesses. With reduced travel times, truck operators and freight companies can save fuel and operational costs, benefiting the broader economy.
The Delhi-Mumbai Expressway tunnel update highlights India’s focus on infrastructure that balances development and ecological preservation, making it a model for future projects.
What’s Next?
Final inspections and trial runs of the Kota Tunnel are underway, with an official inauguration planned once it is fully open. Travelers and commuters can look forward to a seamless, high-speed corridor that connects Delhi to Mumbai in just half the time it currently takes.
