Asia's Longest Elevated Wildlife Corridor Overview
The most technologically advanced section of the greenfield Delhi–Dehradun Expressway is the 12-kilometer elevated viaduct traversing the eco-sensitive Mohan–Ganeshpur forest zone within Rajaji National Park. Built on high concrete pillars, this elevated highway allows wild elephants, leopards, tigers, and deer to migrate freely beneath the roadway without vehicular collision risk.
To preserve the sanctuary environment and prevent wildlife disturbance, NHAI, the Ministry of Environment, Forest and Climate Change (MoEFCC), and Uttarakhand Police enforce strict wildlife driving regulations.
