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.
