As part of the state's fish recovery efforts, WSDOT has made it a priority to reconnect waterways where our roads act as barriers. In western Washington, that means building hundreds of fish passable structures under state highways in the next decade to create habitat gain essential for meeting our fish recovery goals. Beginning in 2023, WSDOT will build multiple structures under I-90 and local roads near Bellevue to restore natural stream conditions in Sunset Creek.
What to expect
I-90 travelers and users of local roads can expect:
- Long-term lane reductions in both directions of I-90
- A single lane of alternating traffic on Southeast 36th Street for up to six months
- A six month full closure of Southeast Eastgate Way, or 12 months of a single lane of alternating traffic
This project is being combined into a single contract with two other fish passage projects on SR 161 and SR 202 and 203. Construction is scheduled to occur from 2023–2026. Because of the multiple locations, we cannot specify at this time when the work will occur on I-90.
