State Route 9 will operate with a single lane near Kalloch Road (milepost 59) starting Aug. 21, with alternating traffic through a bypass road for 42 days until Sept. 14. The change is part of a fish passage construction project along the river.
The Washington State Department of Transportation (WSDOT) states delays are expected in the area. The project aims to improve fish passage for salmon and other species in Nookachamps and Hansen Creeks. WSDOT will maintain the single-lane configuration until Sept. 14, with no further details on traffic management provided.
