State Route 9 is reduced to a single lane near Kalloch Road (MP 59) starting Aug. 3, 2026, with alternating traffic through a bypass road for 42 days until Sept. 14. The work is part of a fish passage construction project for unnamed tributaries of Nookachamps and Hansen Creeks.
WSDOT warns of delays in the area during the construction period. The project webpage provides additional details, including the project's goal to improve fish passage through creek tributaries. The single-lane configuration will continue daily until the Sept. 14 completion date.
