Stormwater Pipe Inspection

The City will begin inspecting its pipes along with cleaning and other services as needed on various roads throughout Sammamish. Work will start 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. Signage and traffic control will be in place when this occurs. Some of the City's major roadways are included in this work including: Issaquah Fall-City Road and Issaquah Pine Lake Road.

24th Street Sidewalk Project

Crews will pave the eastbound lane of Southeast 24th Street between 251st Avenue Southeast and the entrance to the Beaver Lake Lodge Sept. 15 – Sept. 19 between 7 a.m. and 4 p.m. One lane will be closed at a time, with signage and flaggers directing alternating traffic in the other lane. 

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.
