In Agoura Hills, California, construction crews are building what will soon become the world’s largest wildlife crossing—the Wallis Annenberg Wildlife Crossing. This ambitious project spans ten lanes of U.S. Highway 101 and is set to reconnect ecosystems that decades of urban sprawl have split apart. Moreover, it aims to provide a safe path for mountain lions, deer, coyotes, and many other species.
Building for a Wild Future
Conservationists and engineers have come together to bring this $92 million vision to life. In fact, this collaboration between public agencies and private donors—including the Annenberg Foundation—represents one of the most significant urban wildlife protection efforts in U.S. history. Furthermore, the design will feature native plants and noise-reducing features to help wildlife feel at home.
A Legacy of One Lion
P-22, a famous mountain lion, sparked a movement. He crossed two major freeways to reach Los Angeles’s Griffith Park, living out his life as a symbol of resilience—and the risks of isolation. As a result, the crossing now honors his legacy, ensuring that future wildlife will not have to face the same perilous journey.
A Global Model for Conservation
The project is setting an example for cities around the world. Therefore, it shows that urban infrastructure and environmental conservation can—and must—work hand in hand. When it opens by 2026, the Wallis Annenberg Wildlife Crossing will not just protect animals—it will redefine how we coexist with nature.
