State Route 9 will see reduced traffic capacity near Kalloch Road starting August 23, with alternating northbound and southbound traffic through a bypass road for 42 days until September 14. The project aims to improve fish passage in Nookachamps and Hansen Creeks.

Additionally, traffic on SR 9 will alternate between northbound and southbound lanes from 10 a.m. to 4 p.m. Mondays through Thursdays through September 3, just south of Mount Vernon Big Lake Road. These changes are part of the same fish passage construction project on SR 9.

Residents should expect delays in the area during these construction periods. The Washington State Department of Transportation (WSDOT) provides project details on their website.
