State Route 9 will operate with 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. This change is part of fish passage construction work on the project webpage.
WSDOT expects delays in the area during the single-lane operation. The construction aims to improve fish passage at unnamed tributaries of Nookachamps and Hansen Creeks. The project is scheduled to end on Sept. 14, 2026, at 8:00 a.m.
