"Officials have unveiled plans for a grassy bridge over a Southern California highway that would provide a safe and natural passage for mountain lions and other animals migrating between wilderness areas.

The vegetation-lined bridge over the 101 Freeway in Agoura Hills, just west of Los Angeles, would cost $30 million to build and construction could not begin for years, said California Department of Transportation (CalTRANS) spokeswoman Lauren Wonder.

The Mountains Recreation and Conservation Authority, a government agency, funded a CalTRANS report on the proposed bridge and on Wednesday released the document, which said it was achievable."
