Drivers planning a trip on Interstate 90 this weekend should plan to add at least an hour to their trips between Easton and the Cle Elum area, said the state Department of Transportation.
DOT officials advised drivers to avoid even longer delays by leaving early in the morning or later in the evening.
From 9 a.m. Friday until 9 a.m. Sunday, eastbound I-90 will be reduced to two lanes and one lane westbound.
And from 9 a.m. Sunday until 6 a.m. Monday, westbound I-90 will be reduced to two lanes and one lane eastbound.
