Project overview
Reconnecting waterways where roads act as barriers is a priority for the state. In western Washington, this means building hundreds of fish passage structures under state highways to create habitat that is essential for meeting fish recovery goals.
A culvert under State Route 524 in Lynnwood is a barrier to fish migration through Scriber Creek. As early as summer 2026, a Design-Builder working for WSDOT will replace the culvert and rebuild the stream to reopen habitat and restore fish populations.
What to expect
WSDOT will select a qualified design-build contractor to complete the design of the fish passable structures for Scriber Creek. This project is fully funded and combined into a single contract with other fish passage projects on Interstate 5 and SR 522. Construction is currently anticipated to begin in mid to late 2026 and interstate closure needs will be determined by the type of structures and construction method proposed by the Design-Builder. Lane reductions will likely be necessary during select periods of construction in order to build the new culvert structure under SR 524.
While the timing of culvert construction largely depends on the Design-Builder, we anticipate construction could occur periodically over the span of 2 to 3 years. The exact dates and details of construction impacts will be announced closer to construction.
We will post important project updates as work progresses to our social media channels and weekly traffic news email once construction is underway.
By building a new fish passage under SR 524, we can return Scriber Creek to its natural stream conditions and open important spawning habitat to help several species recover.
