LUC has completed the first ever worldwide study of research on green bridges, on behalf of Natural England. We found that green bridges are an effective way of linking wildlife across roads, which means they could become a key aspect of the sustainability of future transport projects.

Natural England were looking to address landscape, access and ecological severance, connectivity and integration issues on the road and rail transport network, and to maximise the delivery of landscape benefits and ecosystem services. We identified and analysed the design and positioning of green bridges and similar infrastructure, including retro-fitting green features to existing grey bridges.

The information contained in the review will help developers and planners factor new green bridges into their construction plans or consider the greening of existing bridges.
