WSDOT announced multiple road closures affecting Puyallup drivers starting this week. Northbound I-405 will close from Northeast 70th Place to Northeast 85th Street from 11 p.m. Friday, Aug. 28 to 5 a.m. Monday, Aug. 31. Southbound I-405 will close up to two lanes from milepost 12 to Coal Creek Parkway Southeast on Sept. 3-4. State Route 547 will alternate traffic with flaggers from 9 a.m. to 3 p.m. weekdays through Sept. 4 for PSE utility work.

The closures aim to complete construction and utility work safely. Drivers should expect delays and use detours where available. The I-405 northbound closure has a signed detour in place. The I-5 near exit 240 will reduce to a single lane nightly from Aug. 31 through Sept. 4 for fish passage construction.
