Project overview
This project will remove a barrier to fish passage along Martha Creek on State Route 524 near Lynnwood. Contractor crews working for WSDOT will remove the existing culvert and replace it with a fish-passable structure. This new structure has the potential to open more than 1.5 miles of habitat for coho salmon and steelhead, sea-run cutthroat and resident trout.
What to expect
WSDOT will select a qualified design-build contractor to complete the design of the fish passable structure for Martha Creek to Swamp Creek. This project is combined into a single contract with other fish passage projects on Interstate 5 and SR 525. Construction is currently anticipated to begin in mid to late 2025 and road closure needs will be determined by the type of structures and construction method proposed by the contractor. Lane reductions will likely be necessary during certain periods of construction. The exact details of travel impacts will be announced closer to construction.
This project will improve fish passage under SR 524 near Lynnwood.
