Construction on the Wallis Annenberg Wildlife Crossing reached a major milestone on Monday.
Workers began laying dirt down on the bridge spanning the 10 lanes of the 101 Freeway in Agoura Hills that will allow wildlife to cross over the freeway safely.
Aerial footage from Sky5 provided a better view of crews working to lay more than 6,000 cubic yards of soil as the sun broke through the clouds Monday morning.

Stretching over 200 feet long and 165 feet wide across the roadway, the bridge – billed as the world’s largest wildlife crossing – will connect two natural landscapes that have long been bisected by one of the nation’s busiest highways.
It is funded through a public-private sponsorship, with $34 million in funding provided by donors, while the state put forward more than $58 million. The price tag for the project was originally estimated to be more than $90 million.
California Gov. Gavin Newsom announced last May that the wildlife crossing should open by early 2026.
