What is the Agoura Hills wildlife crossing project?

The Agoura Hills wildlife crossing project is a $92 million effort to build a 1-acre wildlife crossing over the 101 Freeway, reconnecting the Santa Monica Mountains to the rest of the world for local species.

When will the Agoura Hills wildlife crossing be completed?

The Agoura Hills wildlife crossing project is scheduled for completion in the fall of 2026, with the first phase of 5,000 native plants already planted as of October 2025.

Q: How will the Agoura Hills wildlife crossing benefit mountain lions?

The wildlife crossing is designed to support the mountain lion population in the Santa Monica Mountains, which researchers estimate could become extinct within 50 years due to the freeways acting as barriers to their movement. The crossing will provide a safe passage for mountain lions and other animals to cross the 101 Freeway.

$92M Wildlife Crossing Reconnects Santa Monica Mountains

As of October 2025, the first phase of a groundbreaking $92 million wildlife crossing project in Agoura Hills is underway. Project leaders ceremoniously planted the initial 5,000 native plants on the 1-acre site, which will eventually span 10 lanes of the 101 Freeway at Liberty Canyon Road.

The wildlife crossing is a critical effort to reconnect the Santa Monica Mountains to the rest of the world for local species. It is designed to support a diverse array of animals, including mountain lions, desert cottontails, lizards, bobcats, deer, bats, monarch butterflies, and dozens of bird species. Over one million hyper-local seeds were collected within a five-mile radius, and a dedicated nursery team has been growing the plants for years to ensure the right habitat is established.

Researchers have estimated that the mountain lion population in the Santa Monica Mountains could become extinct within 50 years due to the freeways that act as barriers to their movement. The wildlife crossing, set for completion in the fall of 2026, is a crucial step in preventing this local extinction and restoring the natural ecosystem. It is a public-private partnership that includes contributions from the Annenberg Foundation and various government agencies.
