WSDOT announced multiple road closures affecting Tacoma-area highways beginning Aug. 24. SR 20 near Loup Loup Pass will have alternating one-lane traffic until Aug. 27. I-405's southbound HOV lane closes nightly until Aug. 28. SR 9 near Kalloch Road will have single-lane traffic through Sept. 14 for fish passage construction.

The closures impact daily commutes for drivers traveling through Tacoma. WSDOT advises drivers to expect slowdowns and delays during work hours. Project details are available on WSDOT's website. Some closures, like the I-405 northbound lane closure from Aug. 28-31, will extend into next week.
