Animal Highways: New Ledges Aid Wildlife Underpass
2 Aug
Summary
- Mammal ledges installed in drainage tunnels beneath a new road.
- These create dry pathways for wildlife to safely cross under the road.
- The ledges help species like badgers and hedgehogs reach habitats.

In a thoughtful integration of infrastructure and conservation, mammal ledges have been installed within drainage tunnels along the new A421 dual carriageway. This project, situated between the Black Cat roundabout in Bedfordshire and the Caxton Gibbet roundabout in Cambridgeshire, aims to facilitate safe wildlife passage.
The installed ledges provide crucial dry pathways. These enable small animals to traverse safely underneath the road, preventing them from having to enter the watercourses within the culverts. This proactive measure ensures the continued accessibility of vital habitats for various species.
Specifically designed to benefit animals such as badgers and hedgehogs, these ledges are a testament to National Highways' commitment to wildlife welfare. The initiative ensures that essential species can maintain their movements and access to their territories despite the presence of the new dual carriageway.
