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. 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.

Monitoring Wells Installation

A total of nine monitoring wells will be drilled as part of a future sewer main extension designed by King County. Beginning Oct. 8, a contractor will be on East Lake Sammamish Parkway Northeast between Inglewood Hill Road and 3931 East Lake Sammamish Parkway Northeast to drill and install monitoring wells. Traffic control will be in place during this work. There will be alternating one-lane closures, which may cause some delays. Work will take place from 9 a.m. to 3:30 p.m. and is expected to last approximately 10 to 15 working days.

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.
