US 12 over I-5 will have nightly single-lane closures for bridge repairs from 7:30 p.m. Monday, Aug. 10, to 6 a.m. Thursday, Aug. 20, according to WSDOT.
Travelers should follow a signed detour using northbound I-5 to Exit 71 for SR 508, then southbound back to US 12. WSDOT advises drivers to slow down, stay focused, and expect delays during the work zone.
The closure is part of routine bridge maintenance to ensure safety and structural integrity of the overpass.
