As urban development increasingly encroaches on natural habitats, wildlife faces increasing challenges navigating landscapes broken up by new roads, highways, and housing or commercial construction. Wildlife crossings have become increasingly popular as a modern solution to this pressing issue. These structures are designed to provide safe passage, ensure natural migratory behavior, and enhance human safety by reducing vehicle collisions with animals. One of the most ambitious projects many have been following is the Wallis Annenberg Wildlife Crossing, currently under construction near Los Angeles.

The Wallis Annenberg Wildlife Crossing, set to open in early 2026, promises to provide a safe and sustainable passage for mountain lions and other animals over Highway 101, a massive 10-lane freeway. It will be one of the largest urban wildlife crossings in the world.
Plans for the enormous project were established in 2014 and gained significant traction and major fundraising efforts. The partners on board, including the National Wildlife Federation, the Santa Monica Mountains Fund, and the #SaveLACougars campaign, have made this ambitious project a reality through their joint forts.
