Overview

• Crews began placing the first layers of soil on the Wallis Annenberg Wildlife Crossing on March 31, 2025, a key step in constructing the world's largest wildlife bridge.
• The crossing, spanning 10 lanes of the 101 Freeway, will feature a 1-acre habitat with 6,000 cubic yards of soil and 5,000 native plants to support species like mountain lions, deer, and bobcats.
• The project, launched on Earth Day 2022, is part of a $92-million ecological restoration effort funded by the Annenberg Foundation and other partners, with completion expected in 2026.
• A dedicated native plant nursery has collected over 1.1 million seeds from more than 50 local species to ensure a sustainable habitat, with broader plans to restore 12 acres of open space.
• Experts, including soil scientists, biologists, and engineers, are collaborating to address habitat fragmentation and promote biodiversity in the Santa Monica Mountains.
