State Route 9 will be reduced to a single lane near Kalloch Road (MP 59) starting Aug. 21, 2026, with alternating traffic through a bypass road for 42 days until Sept. 14, according to WSDOT. This work is part of a fish passage construction project for unnamed tributaries of Nookachamps and Hansen Creeks.
The project aims to improve fish passage by modifying creek infrastructure. Drivers should expect delays in the area during the construction period. The alternate traffic pattern will operate daily until the project concludes on Sept. 14.
