Stormwater Pipe Inspection

Crews will inspect and clean stormwater pipes on Southeast 30th Street from 244th Avenue Southeast to 249th Avenue Southeast and Southeast 40th Street from 229th Avenue Southeast to 234th Avenue Southeast, Work will be done June 23-June 27. Traffic disruptions will be minimal, with only occasional single-lane closures expected.

Ziply Fiber Restoration Work

The Ziply permits are currently suspended by the City of Sammamish. Ziply is still allowed to perform restoration work associated with previous construction activities. Restoration activities include soft surface replacement, asphalt patching, and sidewalk replacement.

King County Roads Project

Joints in the metal culvert under the 4600 and 4800 blocks of Sahalee Way NE are failing and water is seeping into the ground, making the soil soft and increasing the danger of slides. Road Services will replace one pipe and rehabilitate another under the road between NE 50th Street and NE 37th Way. This work will require full closure of Sahalee Way NE for five days (June 28 to July 2). All traffic, including emergency vehicles, Metro buses, bicycles, and pedestrians, must use a detour route during the closure. Find updates and details on the project website

WSDOT Traffic Alerts

Traffic Alert: I-90 Lane Closures

Washington State Department of Transportation (WSDOT) crews are continuing repairs on the Interstate 90 project, which will have congestion impacts, especially during peak travel time. These are a continuation of repairs WSDOT began in summer 2022. While this work is occurring, please plan ahead and allow extra time.

State Route 18 Closures

People who use State Route 18 should expect slight traffic shifts during the daytime commute and intermittent nightly lane reductions. This may be as early as 8 p.m. Mondays through Thursdays, with all lanes reopening by 5 a.m. Flaggers will direct motorists when traffic is reduced to one lane. People should continue to plan extra time for their trips, as contractor crews work to widen the highway and redesign the interchange.
