How important are wildlife bridges? Yes, they do apparently exist in The Netherlands, as pictured below, but do they really limit auto vs deer collisions? And are they worth spending a vast amount of money to construct?

Could the same thing be achieved by simply moving deer crossing signs?
Politicians weigh in on the argument.
Canada has wildlife bridges as well (right) but how many wildlife bridges does one stretch of highway need in order to be effective? I live in Southern California and yes, there is a wildlife underpass in the area where I live (under State Route 91 at Coal Canyon). However, I've never see deer road kill on that highway. That may be because traffic is so congested and the cars are moving so very slowly that deer would be able to simply navigate their way by walking slowly between cars. I've never seen a deer do that but an absence of proof isn't proof of absence...
