About Critter Crossings: I-90 Wildlife Overpass

Critter Crossings: I-90 Wildlife Overpass

One of North America's largest wildlife crossings, the I-90 Snoqualmie Pass East project is a series of bridges and underpasses that allow thousands of elk, deer, coyotes, and other species to safely cross the interstate and freely move within their natural habitat. This successful project has reduced traffic collisions by 90% and has recorded over 5,000 animal crossings per year.  

Washington State Department of Transportation (WSDOT) civil engineer Brian White and wildlife biologist Patty Garvey-Darda will explain how this visionary project came to life through collaborations between WSDOT, Unites States Forest and Wildlife Service, Central Washington University and more, to ensure wildlife connectivity is part of the major interstate improvement projects in Washington.  

Patty Garvey-Darda is a wildlife biologist with the USDA Forest Service on the Okanogan-Wenatchee National Forest and serves as the liaison to WSDOT on the I-90 Snoqualmie Pass East project. She holds a B.S. in conservation of natural resources and a master's degree in zoology from University of California, Berkeley. 

Brian White brings more than 35 years of experience as a licensed civil engineer and serves as the Region Administrator for WSDOT's South Central Region. He provides strategic leadership for a region encompassing six legislative districts, more than 3,100 lane miles of state highway, and 532 bridges. Brian is a graduate of Oregon Institute of Technology.

These events are open to everyone interested in Pacific Northwest history, and beyond!

It's like being back in the classroom - except this time you get to settle into comfortable seats and enjoy a drink or two with dinner while you listen and learn.
