I-405, I-90, and I-5 will have overnight and nightly lane closures through Friday, Sept. 4, according to WSDOT. The closures include two lanes of southbound I-405 from milepost 12 to Coal Creek Parkway, two lanes of northbound I-405 from milepost 7 to 8. 5, and the eastbound I-90 off-ramp to Factoria Boulevard.
I-5 will be reduced to a single lane nightly from 8 p.m. to 5 a.m. near Alger/Lake Samish Road for fish passage construction. SR 20 will have alternating traffic with flaggers from Swin Slough Bridge to Laconner Whitney Road for Anacortes utility work. The closures will continue until their expected end dates, with some lasting until Sept. 11.
WSDOT advises drivers to plan ahead and expect delays. The closures are part of ongoing infrastructure and utility projects across the region.
