California plans to break ground on April 22—Earth Day—for what it’s calling the world’s largest wildlife crossing. The bridge will cross 10 lanes of Highway 101 and a feeder road northwest of downtown Los Angeles in an effort to help mountain lions (Puma concolor) and other wildlife cross the major thoroughfare to and from the Santa Monica Mountains. Spanning 200 feet, the $90 million project is being covered by about 60% private donations. The crossing is being named for Wallis Annenberg, the philanthropist whose foundation donated $25 million. Construction is slated to be completed by early 2025.
