Construction is nearing completion in Los Angeles of Wallis Annenberg Wildlife Crossing, described as the world’s largest wildlife bridge. The crossing is 64 meters long and 53 meters wide and runs over the busy Highway 101, aiming to give animals a way to travel freely between separated natural habitats.
The project was prompted by the story of the mountain lion P-22, who became a symbol of Los Angeles after covering dozens of kilometers across highways and settling in an urban park. His story highlighted a serious environmental issue: animals become isolated by the city and cannot meet their peers, which can lead to the weakening of the population.
The project lasted 13 years, required the purchase of dozens of private properties, and raised more than $100 million—mostly through private donations, including from the Annenberg family. The bridge takes into account noise, fire safety, and the landscape so that animals can feel secure.
Similar initiatives are already being implemented across the country, inspired by the Los Angeles example. And P-22 will remain a lasting symbol of how one animal can inspire one of the largest conservation projects.
