State Route 9 near Kalloch Road (milepost 59) will operate with a single lane and alternating traffic through a bypass road starting Aug. 21 for fish passage construction, WSDOT announced. The change will last 42 days until Sept. 14. Drivers should expect delays in the area as the project aims to improve fish passage at unnamed tributaries of Nookachamps and Hansen Creeks, affecting northbound and southbound traffic through the bypass. The project webpage provides additional details.
