184th Pl SE Culvert Replacement


Snohomish County is proposing to replace a culvert under 184th Pl SE, in the Bothell area. The existing culvert is deemed a fish-passage barrier. The new arch culvert is designed to meet fish passage standards..


Construction is expected to begin June 30 and end August 31, 2022. Construction crews will be working Monday – Friday during daylight hours.

Traffic Impact

This project will require a 24/7 full-road closure from June 30 through August 31. There will be a detour route (see map).


The estimated cost for this culvert replacement is approximately $750,000 and will be paid for through Surface Water Utility funds.
