Governor Gavin Newsom Directs $340 Million for Highway Wildlife Crossings and Habitat Corridors

SACRAMENTO — Governor Gavin Newsom and the California Department of Transportation (Caltrans) announced on Monday the distribution of $340 million in state capital funding through the California Transportation Commission to construct fourteen large-scale vegetated wildlife crossing overpasses, subterranean tunnels, and directional exclusion fencing across critical highway choke points along Highway 101 in Agoura Hills, Interstate 15 in the Mojave Desert, and Highway 99 in the Central Valley.

The initiative expands on California's landmark Wallis Annenberg Wildlife Crossing, scaling habitat connectivity statewide to address severe genetic isolation threatening Southern California mountain lion populations and reducing thousands of high-speed vehicle-wildlife collisions that cause fatal motorist injuries and millions in annual vehicle damage.

Engineering Highway Reconnection for Biodiversity and Safety The $340 million allocation funds:

• 14 Vegetated Highway Overpasses and Tunnels: Engineered with sound barriers, native drought-tolerant chaparral landscaping, and natural acoustic buffers spanning up to eight highway lanes.
• 180 Miles of High-Tension Exclusion Fencing: Specialized climb-resistant fencing equipped with one-way escape gates directing wildlife away from roadbeds toward overpasses.
• Wildlife Telemetry and AI Trail Cameras: Infrared cameras and GPS tracking collars monitoring species adoption rates and migration frequencies in partnership with UCLA and UC Davis wildlife biologists.

"California's highways have connected our communities for generations, but they have also cut off critical wildlife migration corridors and put motorists in harm's way," Governor Gavin Newsom said during an announcement in Ventura County. "By investing $340 million in state-of-the-art wildlife crossings, we are protecting our iconic biodiversity, preventing dangerous collisions on our freeways, and building a more resilient transportation network for the future."

Highway safety advocacy groups, conservation non-profits, and insurance coalitions commended the governor's allocation, noting that every dollar invested in highway wildlife crossing infrastructure yields over $2.50 in averted emergency medical services, vehicle repair claims, and traffic delay costs.
