India’s first 8-lane tunnel beneath a tiger reserve is scheduled to open on June 20, 2026, according to reporting. The tunnel is being built under Rajasthan’s Mukundra Hills Tiger Reserve as part of the Delhi–Mumbai Expressway. The project consists of a 4.9-kilometer, twin-tube tunnel designed to carry expanded traffic capacity across the expressway corridor.
The outlets describe the tunnel as an “engineering marvel” and say it is expected to reduce travel times and improve connectivity between major regions served by the Delhi–Mumbai Expressway. At the same time, the project is framed as prioritizing wildlife conservation because of its location beneath a protected tiger reserve.
The coverage focuses on the opening date, location, and basic technical details—such as the 8-lane capacity and the tunnel length—while emphasizing the dual aim of easing travel and managing environmental considerations associated with construction beneath a wildlife habitat.
