Los Angeles is infamous for its many freeways and horrible traffic. But it can soon be known for something more positive: the creation of the world's largest wildlife bridge. Located in Agoura Hills in western L.A. County, the proposed Wallis Annenberg Wildlife Crossing will measure 200-foot-long and 165-foot-wide when completed, and span over a busy eight-lane stretch of the 101 Freeway that is used by about 300,000 vehicles daily.  

This massive project is supported by various public and private organizations, including the California Department of Transportation and the National Wildlife Federation. Construction is set to begin in early 2022 and anticipated to be completed by October 2023. The project will be divided into two phases: the first will cover the area across the 101 Freeway and the second will cover the two-lane stretch across Agoura Road. The bridge is designed to look like part of the natural landscape with native vegetation and irrigation systems. It will shield animals from the commotion below with sound walls and light deflectors to mitigate the effects of the noise and glare of headlights.
