"Lonely Mountain Lion Inspires World's Largest Wildlife Overpass"

A mountain lion named P-22, trapped by L.A. freeways, became a celebrity and inspired the construction of the world's largest wildlife overpass. The Wallis Annenberg Wildlife Overpass, funded by private donations including $26 million from philanthropist Wallis Annenberg, aims to help animals safely cross the busy six-lane 101 Freeway in Los Angeles. The overpass includes specially designed sound walls and light barriers to reduce noise and deter animals from turning back. Wildlife crossings have proven successful in other countries, and this project will also restore the surrounding landscape and create an ecosystem on top of the overpass. P-22's story has ensured a future for other mountain lions in the region.
