Stormwater Pipe Inspection

The City is inspecting its pipes along with cleaning and other services as needed on various roads throughout Sammamish. Work started Sept. 23 and is expected to last until the end of the year. There will be some traffic disruptions, but they are expected to be minimal, with occasional single-lane closures.

Ziply to work on communications lines

Ziply will be working on installing new fiber lines starting. This work involves trenching in the right of way and in the public utility easement that is predominantly in-residence front yards. There may be some minor traffic impacts.

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.
