Multiple road closures and lane restrictions begin this week for repairs and construction in Longview. The Washington State Department of Transportation (WSDOT) has announced several temporary changes to local highways and roads effective August 18, 2026.

WSDOT will close one general-purpose lane of eastbound SR 522 from Campus Way Northeast to 131st Avenue Northeast nightly from 8 p.m. on August 18 until 4:30 a.m. on August 21. A single lane of US 12 over I-5 will close nightly for bridge repairs from August 10 to August 20. Additionally, multiple lanes on I-405 and SR 508 will be closed or restricted during specific time frames.

Travelers should expect delays and follow signed detours. The US 12 closure requires using a detour via northbound I-5 to Exit 71 for SR 508, then southbound back to US 12. The SR 9 closure south of Mount Vernon Big Lake Road will remain in place until 6 a.m. on August 19.
