LOS ANGELES – Governor Gavin Newsom announced on June 25 that the final phase of the Wallis Annenberg Wildlife Crossing has begun. What is soon to be the world’s largest wildlife crossing will connect open space on both sides of US Highway 101 in Agoura Hills and is expected to be completed by fall 2026.

The final phase of this project includes extending the wildlife crossing over a two-lane local road. The work involves significant earthmoving, restoration of natural hydrology, protection of heritage oak trees, and coordination with multiple agencies to relocate essential utilities along the freeway corridor.

The first phase of construction was completed this year and included over 26 million pounds of concrete, 82 bridge girders, vegetated sound walls, habitat rock features, and living soils to support native plant growth. Caltrans and partners laid 6,000 cubic yards of living soil across the bridge structure in preparation for planting this fall, which will include over 50 native species and restore the wildlife habitats both on the crossing and in surrounding open-space areas.
