India is making history with the opening of the first eight-lane road tunnel in the country that is built under a tiger reserve. The tunnel is part of the ambitious Delhi-Mumbai Expressway project and is expected to be opened to traffic on 20th June, according to several media reports.
The 4.9 km-long tunnel will be built under Mukundra Hills Tiger Reserve, one of the most unique highway projects in the country. The tunnel is designed to be both practical and aesthetically pleasing, ensuring that it seamlessly integrates with the natural environment and allows for easy passage for animals.
The tunnel is expected to be a work of engineering and environmental design, with a focus on minimizing its impact on the local ecosystem and ensuring that it is both functional and aesthetically pleasing for the animals' movement.

Part of the Delhi-Mumbai Expressway
The tunnel is an integral part of the 1,386 km long Delhi-Mumbai Expressway, one of India's biggest infrastructure projects. It is expected to cut down the travel time from Delhi to Mumbai from more that 24 hours to nearly 12 hours once it's fully operational. It will also enhance connectivity between states of Haryana, Rajasthan, Madhya Pradesh, Gujarat and Maharashtra and will help reduce the logistics cost.
The Kota tunnel was one of the last remaining bottlenecks in the expressway corridor, reports said. Once finished, drivers will experience more efficient and better driving experiences.
