Wildlife crossing over the 101 Freeway in Agoura Hills closer to completion

AGOURA HILLS, Calif. (KABC) -- A major wildlife crossing for the 101 Freeway in Agoura Hills is taking another big step forward.

Crews are expected to pour 850 tons of wet concrete for the foundation of the bridge.

The project will allow animals to move safely above the 101 Freeway at Liberty Canyon.

Once completed, it's expected to be one of the world's largest wildlife animal crossings.

Biologists hope the crossing will expand the mountain-lion mating pool.
