First of all, these overpasses and underpasses are extremely effective. When we installed these overpasses, we also installed cameras. When wildlife cross these various laneways, we have actual photos of grizzly bears, cougars, and elk that are using these overpasses and underpasses.
It's quite interesting. Last year one of our parks staff gave a presentation in Washington, D.C. It was at a conference on innovative technology for highway transportation, looking at it from an ecological perspective. In fact it was one of the award-winning presentations, just because of its innovation and also the types of results it's bringing forth.
