World's largest wildlife migration bridge planned over big freeway near Santa Monica Mountains NRA

Engineers in southern California are hard at work designing the biggest wildlife corridor in the world, to extend over US Highway 101 to the north-west of Los Angeles.

The corridor will connect different parts of the Santa Monica Mountain chain, which is crucial to the future of mountain lions – but it will help other species as well. The $87m bridge has entered its final design phase and is on track to open in 2023.
