Delhi-Mumbai Expressway: India’s first 8-lane tunnel beneath a tiger reserve is set to open on June 20; everything travellers need to know

From timesofindia.indiatimes.com - 15 June 2026, 21:53

India is set to open its first eight-lane road tunnel beneath the Mukundra Hills Tiger Reserve in Rajasthan, marking a major milestone on the Delhi–Mumbai Expressway. The 4.9 km tunnel has been designed to improve connectivity while minimising impacts on wildlife, demonstrating how large-scale transport infrastructure can be integrated with environmental protection. Once the expressway is fully operational, travel time between Delhi and Mumbai is expected to be reduced significantly.

Finland's Onkalo Repository Nears Opening as World's First Permanent Nuclear Waste Facility

From www.sciencealert.com - 15 June 2026, 15:28

Finland is preparing to open the world's first permanent deep geological repository for spent nuclear fuel. Located more than 400 metres underground in stable bedrock, the Onkalo facility represents a major milestone in underground engineering, demonstrating how deep underground infrastructure can provide a long-term solution for the safe disposal of radioactive waste.
