Pilchuck Creek Br 626 Replacement


To lessen the impact of heavy truck loads and other oversized vehicles, Pilchuck Creek Bridge 626 was reduced to a single lane with weight restrictions in July 2021. The bridge is located just north of 236th NE on Pacific Highway (Old SR 99), approximately 2.5 miles northeast of Silvana and 8 miles southeast of Stanwood.

Built in 1933, the three-span, 180-foot steel and concrete structure is showing normal signs of deterioration due to age, including a worn bridge deck and cracking throughout. The county plans to replace the existing bridge with a single span structure that will clear the floodplain and provide two vehicle lanes and pedestrian access to the Stillaguamish Tribes' Lower Pilchuck Creek Wildlife Preserve. 


Construction of the new bridge is anticipated to begin in 2027.

Traffic Impact

  • The single lane revision may cause minor delays for residents in peak travel periods.
  • Some large, multi-axle vehicles will be required to detour on Interstate 5. Please check the Height and Weight Restrictions page for additional information.
  • Traffic impacts during the construction of a replacement bridge are under review.


The county received a $8,220,000 grant from the Washington Department of Transportation (WSDOT) Federal Local Bridge Program in 2022.
