268th St NW Culvert Replacement


Snohomish County is scheduled to replace the existing culverts at the 268th St NW crossing of Secret Creek, near Stanwood, during summer 2021. The existing 24-inch and 18-inch concrete culverts have been deemed a fish-passage barrier. The project will replace the parallel culverts with a single 18-foot span, 10-foot rise, by 70-foot long culvert.

Snohomish County and the construction contractor will be practicing COVID-19 prevention protocols during this project. Please give crews six feet for social distancing.


Construction for this project is scheduled for July through the beginning of September 2021.

Traffic Impact

A three-week road closure will be required for this project in the 1300 block of 268th St NW with a signed detour. The assigned detour route will use 28th Ave NW, 276th St NW/Beck Rd, Old Highway 99, 12th Ave NW, and 268th St NW.


Construction for this project is estimated at $715,000 and will be funded through the Surface Water Management Utility Fund.
