US 12 over I-5 will close nightly from 7:30 p.m. Monday, Aug. 10 to 6 a.m. Thursday, Aug. 20 for bridge repairs, according to WSDOT. The closure affects milepost 66.5 and will require drivers to follow a detour using northbound I-5 to Exit 71 for SR 508, then southbound back to US 12.
Travelers should expect delays during the closure period, with flaggers directing traffic to the detour. The work is part of bridge maintenance and is scheduled to end by Aug. 20, 6 a.m., when normal traffic flow will resume.
