State Route 9 near Kalloch Road (MP 59) will operate with a single lane beginning Aug. 3, 2026, for 42 days due to fish passage construction, according to WSDOT.
Drivers should expect delays as alternating traffic flows through a bypass road. The closure ends Sept. 21, 2026, at 8 a.m.
WSDOT’s construction update notes the work is part of a fish passage project. No additional details on project scope or funding were provided in the public notice.
