LA Times | This architect is trying to save cougars from becoming roadkill on California freeways

Architect Robert Rock is facing a Herculean task: Design a bridge that will allow mountain lions to cross safely over a stretch of the 101 Freeway that roars with the traffic of 300,000 vehicles each day.

The terrain was as challenging as could be. But Rock could see the future — cougars who would otherwise become roadkill crossing a proposed $87-million bridge so that they could roam, find prey and mate.
