I-90 Wildlife Bridges Coalition

The I-90 Wildlife Bridges Coalition formed in 2004 to ensure safe passage for wildlife and people at Interstate 90 in Washington's Cascades. The first wildlife bridge is scheduled to begin construction in 2015.

Connecting habitat in the Cascades helps large mammals roam more freely north to south within Washington. The I-90 Wildlife Bridges Coalition, administered by Conservation Northwest, was formed to make sure the I-90 Project interstate upgrade incorporates over- and underpasses for wildlife to safely negotiate the interstate. 

The I-90 Project will improve 14 key animal-travel areas between Hyak and Easton, and includes two wildlife bridges.

This plan to improve connectivity around Snoqualmie Pass is the natural outcome of The Cascades Conservation Partnership, and earlier project spearhead by Conservation Northwest to connect Alpine Lakes to Mount Rainier.

The I-90 Project

The  I-90 Snoqualmie Pass East Project focuses a critical 15-mile stretch of interstate along a busy passage near Snoqualmie Pass in the Cascades, making it safer for people and wildlife. Improvements to the freeway include crossing structures to divert wildlife over and under the freeway.

Underpasses include creek crossings, wildlife-size culverts, and several underpasses, including the crossing at Gold Creek, which is now complete. In 2012-13, scores of volunteers planted a thousand native plants to restore wildlife habitat around Gold Creek.

Two fully vegetated, 150-foot-wide overpasses are planned. Construction on the Price-Noble wildlife bridge is expected to start in 2015. It will be Washington's first-ever wildlife bridge.
