WSDOT announced multiple lane closures for Everett-area highways this week, including I-405 and SR 522. The left express toll lane of northbound I-405 will be closed nightly from 8:30 p.m. Monday, August 17, to 5 a.m. Friday, August 21. A single lane of US 12 over I-5 will close nightly from 7:30 p.m. Monday, August 10, to 6 a.m. Thursday, August 20, for bridge repairs.

The closures affect daily commutes and require drivers to follow signed detours. For example, travelers crossing US 12 over I-5 will be directed to take northbound I-5 to Exit 71 for SR 508, then southbound back to US 12. WSDOT warns drivers to slow down, stay focused, and expect delays.

Additional closures include a single lane of southbound I-405 from Coal Creek Parkway Southeast to milepost 8. 63, closed nightly from 10:30 p.m. Wednesday, August 19, to 5 a.m. Friday, August 21. The southbound I-5 near Klickitat Road will close one right lane daily from 8:30 a.m. to 2:30 p.m. through Thursday, August 20, for maintenance.
