Sexton Rd Culvert Replacement

Snohomish County Surface Water Management (SWM) and Washington State Department of Transportation (WSDOT) are collaborating to remove a fish passage barrier on Sexton Creek at Sexton Rd and US-2. The county project includes replacing twin culverts under Sexton Road with a 27-foot span buried bridge and removal of a series of downstream weirs. WSDOT will also be replace twin culverts under US-2 with a bridge structure and restore the stream channel between the culvert replacements. Together, approximately 550 lineal feet of channel will be restored to a natural condition beginning at the confluence of Sexton Creek with the Pilchuck River.


Construction is tentatively scheduled for 2026.

Traffic Impacts

Construction will likely require a full 24/7 closure at 7616 Sexton Rd from July to September. More information will be available once construction is scheduled.
