Southern California has many animals like deer, foxes, and mountain lions. But their homes are split up by many roads and highways. U.S. Route 101 is one of these big freeways. It stretches about 808 miles.
Cars often speed on these freeways. This creates a big problem for animals trying to cross, leading to many collisions. Each year, about 1 million to 2 million crashes between wildlife and vehicles happen in the U.S. These crashes cause about 200 deaths, 26,000 injuries, and over $8 billion in costs.
Building a Safe Passage
To solve this, California started building the Wallis Annenberg Wildlife Crossing in 2022. This overpass goes over 10 lanes of Route 101 in Agoura Hills. After four years of building and 30 years of planning, it should be finished in early December 2026. It will be the biggest wildlife crossing in the world.

The crossing won't just be a simple bridge. It will be covered with plants native to the area. This design makes it look like a natural habitat, helping animals cross one of the busiest freeways safely.
Hope for Wildlife
The project was partly inspired by the deaths of mountain lions, including P-22, a famous cougar in Los Angeles. His story helped gather public support for the crossing.
Beth Pratt, California's regional executive director for the National Wildlife Federation, is excited about the project. She said it shows what's possible. "You’re going to see this ecological transformation," Pratt noted. "We can redeem a freeway."
Pratt announced on Earth Day that the crossing will officially open for animals on December 2. Recently, a hummingbird was seen on the habitat of the 101 structure, even before it was finished.
Another wildlife overpass in California also saw its first visitors recently. Three mule deer crossed over Route 97 in Siskiyou County while that bridge was still being built. Caltrans District 2 shared that it's amazing to see wildlife using the new structure already. These crossings are designed to give animals a safer way to cross highways and reduce collisions.
