Southeast 24th Street Sidewalk Improvements

Crews are installing a new storm drainage system and constructing a new sidewalk and bike lane on Southeast 24th Street. Work is expected to last until Aug. 16. Crews will work between the hours of 7 a.m. to 5 p.m. Mondays through Fridays. During construction, traffic will often be reduced to a shared lane controlled by flaggers. Driveway access may also be temporally restricted. Drivers should use caution and expect delays. Access to the parking lot will be maintained throughout construction.

Road maintenance on 244th Avenue Northeast near Redmond Fall City Rd (SR-202)

This is a King County Local Services project.

Due to a slide occurring in winter 2020, both lanes of 244th Avenue Northeast are narrowed until the impacted support wall can be repaired. Soil samples yielded unexpected data, which caused the design phase to be extended. The repair of the support wall is expected to begin July 8, 2024 and will last approximately six weeks. During this time 244th Avenue Northeast near SR 202 will be fully closed in both directions and a detour plan will be put in place. The King County Road Services Division has a 24/7 Road Helpline - (206) 477-8100. Please plan ahead for delays and extended travel times. For more information please visit the project webpage.

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.
