India is taking a significant step toward balancing development and conservation with the upcoming Delhi–Dehradun Expressway, which will feature Asia’s longest elevated wildlife corridor. Designed to drastically reduce travel time while safeguarding biodiversity, this project is being lauded as a pioneering example of sustainable infrastructure.
The Delhi–Dehradun Expressway is a 210 km, six-lane access-controlled greenfield highway under the Bharatmala project. Estimated to cost over ₹12,000 crore, the expressway is being developed in four phases and is expected to be fully operational by mid-2025, with some phases already partially open to the public.
As the longest wildlife corridor in Asia, it will have raised roads, tunnels, and underpasses for animal crossings. Using its camera, the Wildlife Institute of India (WII) has documented elephants regularly using the corridor. The infrastructure will also include sound barriers to lessen noise pollution, non-intrusive yellow lighting, and vegetation surrounding the main buildings. Additionally, protective fencing will be installed to keep animals out.
What makes this expressway truly special is its 12–14 km long elevated wildlife corridor, the longest of its kind in Asia. Located primarily near the Rajaji National Park, this corridor ensures uninterrupted movement for wild animals across the forested zones of Uttarakhand and Uttar Pradesh.
The Delhi–Dehradun Expressway is more than just a highway—it is a symbol of India’s evolving priorities, where development and environment go hand in hand. By featuring Asia’s longest wildlife corridor, it ensures that progress doesn’t come at the cost of nature.
As the expressway prepares to fully open by mid to late 2025, it promises a faster, greener, and more responsible travel experience for millions of commuters and nature lovers alike.
