WSDOT is reducing State Route 9 to a single lane near Kalloch Road (MP 59) with alternating traffic through a bypass road starting Aug. 3, 2026, for fish passage construction. The project will continue until Sept. 14, 2026, with expected delays in the area.
The project aims to improve fish passage at unnamed tributaries of Nookachamp and Hansen Creeks. WSDOT states the single-lane operation will allow for construction work to proceed safely. Drivers should expect delays during the 42-day project period.
The project webpage provides more details. No further changes to the schedule are listed in the public records.
