India’s first 8-lane tunnel under tiger reserve opens on Delhi-Mumbai Expressway

India is opening its first-ever eight-lane road tunnel built under a tiger reserve, marking a major achievement in road and transport development. The tunnel is part of the Delhi-Mumbai Expressway and is located near Kota in Rajasthan, passing under the Mukundara Hills Tiger Reserve.

This new tunnel is expected to make travel faster, safer and smoother for people travelling between Delhi and Mumbai. At the same time, it has been specially designed to protect animals and their natural habitat.

The tunnel is 4.9 kilometres long and is considered one of the most unique road projects in India. It allows vehicles to move underground while wildlife can move freely above the surface without disturbance.

The Delhi-Mumbai Expressway is one of India’s biggest highway projects. It stretches around 1,386 kilometres and is being built at a cost of nearly Rs 95,000 crore. Once fully complete, it will become one of the country’s most important road links.

This tunnel is seen as one of the final key parts of the expressway and shows how modern infrastructure can grow without harming nature.

Balancing speed and nature

Building a tunnel under a tiger reserve was not easy. The Mukundara Hills Tiger Reserve is an ecologically sensitive area where many animals live, including tigers, leopards and deer.

Normally, building a highway through such a forest can disturb wildlife. Roads often break animal paths and increase the risk of accidents between vehicles and animals. To avoid this, engineers came up with the idea of building the road underground.

This way, animals can continue moving above the tunnel naturally, without crossing busy traffic.

Construction took nearly four and a half years because the work had to be done very carefully. Engineers used special methods to reduce noise, vibration and environmental damage.

The project is important because it shows that development and environmental protection can happen together.

Many experts believe this could become a model for future road projects in forest areas.

The tunnel also has advanced safety systems. These include:

• CCTV cameras for monitoring

• Emergency exits

• Ventilation systems

• Fire safety equipment

• Bright lighting for visibility

• Control rooms for managing traffic

These features will make travel safer for passengers.

Faster travel for millions

The biggest benefit of this tunnel will be faster travel. The Delhi-Mumbai Expressway is being built to cut the travel time between the two cities by half.

At present, travelling by road from Delhi to Mumbai can take more than 24 hours. Once the expressway is fully ready, the journey may take only about 12 hours.

This will save both time and fuel.

The expressway is designed for vehicles to travel at speeds of up to 120 km/h. Since it is an access-controlled highway, there will be fewer stops, no traffic lights and less congestion.

This means:

• Faster movement of goods

• Better transport for businesses

• Lower fuel costs

• Less pollution due to smoother driving

• Easier travel for tourists

Truck drivers and transport companies are expected to benefit greatly because delivery times will become much shorter.

The new tunnel will also improve road safety because vehicles will not have to drive through forest roads where animal crossings are common.

Connecting major states

The Delhi-Mumbai Expressway starts near Sohna in Gurugram and ends at the Jawaharlal Nehru Port in Mumbai.

It passes through:

• Haryana

• Rajasthan

• Madhya Pradesh

• Gujarat

• Maharashtra

This route connects many industrial cities, business centres and transport hubs.

It is expected to boost trade between North and West India.

Tourism may also get a boost as travel becomes quicker and easier. People travelling to Rajasthan, Gujarat and Maharashtra may save many hours.

The expressway has been built with future growth in mind. Right now, it has eight lanes, but it can be expanded to 12 lanes later if traffic increases.

This makes it a long-term investment for the country.

The opening of this tunnel is not just about a road. It represents India’s growing focus on smart planning, modern engineering and environmental care.

As the Delhi-Mumbai Expressway moves closer to completion, this tunnel stands out as a symbol of progress. It shows that India is building faster roads while also respecting its forests and wildlife.

For travellers, businesses and the economy, the benefits could be huge in the coming years.
