Westbound Interstate 90 will be reduced to one lane at 9 p.m. Sunday, June 18, between Preston and Issaquah. The lane reduction will remain in place 24 hours a day for one week.
The freeway currently is reduced to two lanes so contractor crews working for the Washington State Department of Transportation can repair and repave part of a bridge deck. The current closure will end by 6 a.m. Sunday, June 18, to allow for heavy weekend traffic before the second lane reduction begins that evening.
Starting Sunday night, June 18, the contractors need to reduce westbound I-90 to one lane, 24 hours a day, to fully access the center lane and provide a safe work zone for people repairing the freeway. That work will finish by 6 a.m. Sunday, June 25.
Expect westbound I-90 delays
People who rely on I-90 should plan for delays next week—reducing this section of freeway to one lane earlier this spring produced 1- to 4-mile backups, with the biggest delays occurring during the morning commute.
People whose destination is in the Green River Valley south of Renton should consider using State Route 18. There also is construction on that highway, though. People in North Bend and Snoqualmie should consider using SR 202 and Issaquah-Fall City Road. Highway users should plan for delays on any alternate route they choose.
