Our progress correcting barriers

As of June 2022, we completed 379 fish passage barrier corrections statewide. This improved access to approximately 1,301 miles of upstream habitat for fish. Of the 379 statewide corrections, WSDOT corrected fifteen fish passage barriers last year, fourteen of which were in the injunction area, opening 98 miles of stream habitat.

Learn more about our progress identifying and correcting fish passage barriers, and related activities, in our 2022 WSDOT Fish Passage Performance Report (PDF 8.8MB).

Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.

Prep your car. Fill up your gas tank,

pack jumper cables, ice scraper, warm clothing, snacks and water.
