After the soil is laid across the nearly 1-acre native wildlife habitat site, about 5,000 native shrubs and wildflowers collected from the surrounding area will be planted on the crossing.

Officials said it will take several weeks and about 6,000 cubic yards of soil to build the foundation for the 1-acre wildlife habitat being created over 10 lanes of the 101 freeway in Agoura Hills. The project is designed to provide a safe crossing for mountain lions, deer, bobcats and other animals.

The Wallis Annenberg Wildlife Crossing will allow mountain lions, bobcats and other wildlife to travel between the Simi Hills and the Santa Monica Mountains over a 10-lane freeway.
