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.
The county received a $8,220,000 grant from the Washington Department of Transportation (WSDOT) Federal Local Bridge Program in 2022.
Construction schedules are subject to change based on many factors that include: public safety; availability of funding, staffing, equipment and materials; right of way issues; permitting requirements; coordination with utilities and other agencies; soil conditions under roadway and seasonal changes.
