The improvement projects on I-90 near Snoqualmie Pass, WA have been ongoing for a couple of decades now. The Washington Department of Transportation started the operation back in the late-90s to improve road conditions, and alleviate the risk of avalanches closing the highway.
WDOT also partnered with local conservation groups to create multiple animals crossing along the route. Nearly 14,000 animals have been documented using the various underpasses and the Keechelus Lake Overcrossing. The awesome video below documents the success of these projects.
Here’s to hoping more states adopt highway overcrossings for wildlife. They’re a win-win for animals and motorists alike!
