The Wallis Annenberg Wildlife Crossing is poised to become the world's largest wildlife bridge, with a staggering cost of £85 million. This ambitious project, located in the United States, is currently under construction and aims to link the Santa Monica Mountains and Simi Hills over the busy 101 Freeway in Agoura Hills, California.
A Vital Connection for Wildlife
Spanning ten lanes of traffic, the bridge is scheduled for completion by the end of 2026. It will provide a safe passage for a diverse range of species, including coyotes, cougars, deer, mountain lions, and even butterflies, according to reports. The crossing is designed to address the critical barrier posed by the 101 Freeway, which has long fragmented the region's ecosystem.
Reconnecting Fragmented Habitats
The Wallis Annenberg Wildlife Crossing stated: "Of all the area roads, multiple research and planning efforts have identified the 101 Freeway as the most significant barrier to the ecological health of the region. This crossing will re-connect an entire ecosystem that has long been fragmented by this almost impenetrable obstacle for wildlife."
By building over the freeway and an access road, the project will re-establish ecological connectivity for native plant and animal species in the Santa Monica Mountains ecosystem. Rorie Skei, Chief Deputy Director of Santa Monica Mountains Conservancy, expressed excitement about entering the final phase, noting it delivers on over 30 years of work to preserve habitat linkages.
Global Wildlife Crossing Projects
Other notable wildlife bridges include the newly constructed Greenland overpass in Colorado. In the UK, the Gloucestershire Way bridge is set for completion by 2027 and will become Britain's largest wildlife crossing, designed to protect the Cotswolds' natural habitats and animal populations. These projects highlight a growing global emphasis on conservation efforts to mitigate human infrastructure impacts on wildlife.
