Up to two lanes of southbound I-405 will close nightly from 11 p.m. to 4 a.m. between mileposts 18.11 and 16.45 from Monday, July 27 through Friday, July 31. The center lane of southbound SR 527 will close nightly from 9 p.m. Monday through 12 a.m. Thursday, July 30. A collision on US 395 near Blue Creek Road is causing a single-lane closure from 6:10 a.m. to 1:30 p.m. on July 28, with a detour in place. WSDOT states flaggers and pilot cars will direct traffic during the closures. The agency recommends drivers allow extra time for travel during these periods.
