State Route 9 near Kalloch Road (MP 59) will operate as a single lane with alternating traffic through a bypass road starting Aug. 3 and lasting until Sept. 14, according to WSDOT.
WSDOT states the project aims to improve fish passage at unnamed tributaries of Nookachamps and Hansen Creeks. Drivers should expect delays during the 42-day construction period.
The alternate traffic pattern will continue through Sept. 14, with no specific end date provided beyond that date in the public notice.
