The World’s Largest Animal Crossing Bridge Breaks Ground in California

Crossing a huge 10-lane highway in Southern California, the Wallis Annenberg Wildlife Crossing will be the largest animal bridge in the world when it completes in 2026.

Stretching across the 101 highway in the Santa Monica Mountains, the $92 million wildlife crossing bridge will serve over a dozen animal species that call the area home. Instead of being trapped on either side of the highway, or attempting to cross deadly traffic, animals will be able to traverse the manmade environment on a bridge that is full of living plants, trees, and more.

We love the way that animal crossings blend natural environments into the busy manmade landscapes of concrete and steel. It should cut down on unfortunate wildlife deaths that occur when animals attempt to cross the massive, fast-moving ten lane highway.

Located in Agoura Hills, California, the large crossing broke ground this spring, and will complete in early 2026.

Meant solely for wildlife, the bridge is the largest of its kind in the world, and should protect native species that call the area home.

A view from above shows the way the animal bridge brings the natural landscape above the existing built highway and adjacent road.

Animals like mountain lions live in the area, and are the largest wildlife that will regularly use the crossing.

The wildlife crossing supports over a dozen native species, including bobcat, golden eagles, gopher snakes, mountain lions, and more.
