This is the Wallis Annenberg Wildlife Crossing under construction over the 101 just outside Los Angeles, California.

  • Role: subject
  • In the article: The video opens at the crossing under construction over the ten-lane 101, described as the largest of its kind, costing about $92 million. It returns to it for the low-kill-rate-at-high-traffic argument and the isolated southern California cougars it is meant to help.
