Wildlife Crossing Over LA Freeway Nears Completion Amidst Ongoing Construction

The Wallis Annenberg Wildlife Crossing, a major ecological project spanning the 101 Freeway in Los Angeles, remains on schedule for its December 2 opening despite visible ongoing construction. Recent photographs reveal that crews are still engaged in the final stages of the $92 million project in Agoura Hills.

Organizers from the California Natural Resources Agency have expressed confidence that the opening date will be met. A ribbon-cutting ceremony is planned at the site, with a public celebration to follow at King Gillette Ranch. Despite the continued work, the agency stated that December 2 is the confirmed date for the crossing to become available to wildlife.

As part of the ongoing construction, a section of Agoura Road beneath the crossing is scheduled for weekday daytime closures through November 30. These closures are necessary for bridge work and backfill operations, according to local reports. This leaves minimal time between the scheduled end of road closures and the crossing's opening.

The official website for the crossing acknowledges that "some planting and finishing work will continue after opening." The project is being executed in two phases. The first phase, which included the vegetated bridge over the 101 Freeway, was completed in June 2025. The second phase involves the crossing over Agoura Road, utility relocations, earthwork, and habitat restoration.

Initial plans had targeted a 2025 completion, but record rainfall and flooding in consecutive springs significantly impacted the construction schedule. Once operational, the vegetation-covered bridge is intended to serve as a vital corridor, reconnecting divided habitats in the Santa Monica Mountains and allowing animals like mountain lions to travel between areas separated by the freeway.

The 101 Freeway has historically posed a significant barrier to wildlife movement in the region, isolating animal populations. The new crossing aims to mitigate this by providing a safe passage, covered in native vegetation to blend with the environment and facilitate natural movement.
