A mountain lion was found dead on the 101 Freeway, less than half a mile from the steel and concrete endoskeleton of the Wallis Annenberg Wildlife Crossing.

On June 15, 2024, a mountain lion was struck and killed on the 101 Freeway in Agoura Hills, less than half a mile from the under-construction Wallis Annenberg Wildlife Crossing. This incident underscores the necessity of the wildlife bridge, set to be completed by early 2026, which aims to provide a safe passage for animals across the freeway, reducing wildlife fatalities and supporting genetic diversity for species in the Santa Monica Mountains. Local officials and wildlife advocates expressed both heartbreak over the recent death and relief that the wildlife crossing is becoming a reality, emphasizing its critical role in preventing further losses.
The California Highway Patrol reported the fatal accident early in the morning, with the deceased lion later identified as an uncollared adult male by the California Department of Fish and Wildlife. Genetic samples were collected to learn more about the lion's origins. This tragic event, along with previous similar incidents, highlights the ongoing dangers faced by wildlife in the area and reinforces the importance of the crossing, which is designed to benefit a range of species, from mountain lions to monarch butterflies.
Construction of the Wallis Annenberg Wildlife Crossing is progressing, with current efforts focused on building vegetated sound walls and preparing the bridge for soil and plant integration by the end of the year. The project, costing $92 million, will also extend over Agoura Road and include fire-safe utility relocations. Advocates hope the successful implementation of this crossing will inspire similar projects in other critical locations, addressing widespread wildlife movement challenges across busy roads.
