Agoura Hills, California — High above the roaring 10-lane Ventura Freeway (US-101), where 300,000 cars blast through daily, sits what promoters once hailed as the “world’s largest wildlife crossing.” The Wallis Annenberg Wildlife Crossing — a vegetated concrete overpass spanning 210 feet long and up to 174 feet wide — was supposed to be a gleaming symbol of environmental innovation. Instead, as of early 2026, it stands as a textbook case of government waste.
