The Wallis Annenberg Wildlife Crossing, a $114 million conservation project spanning the 101 Freeway in Southern California, is nearing completion. Designed to reconnect habitats in the Santa Monica Mountains for mountain lions and other wildlife, the massive structure is 210 feet long and 174 feet wide.

While the project originally faced budget increases and delays due to inflation and weather, a public ribbon-cutting ceremony is scheduled for December 2 at King Gillette Ranch. Recent construction activities have necessitated local traffic adjustments, including an extended closure of Agoura Road to allow crews to remove temporary supports following weather-related impacts.
