Westbound I-90 lane reductions east of Issaquah start Monday morning, April 10

Several multi-day closures necessary to repair bridge decks

POSTPONED: Work the weeks of May 14 and May 21 has been postponed. The work will be rescheduled in June.

ISSAQUAH – Multi-day lane reductions will return to Interstate 90 between Preston and Issaquah starting Monday morning, April 10. The westbound interstate will be reduced to one lane, 24 hours a day, six times this spring. There also will be two eastbound lane reductions.

The closures will be similar to those that took place in summer 2022, when the freeway was reduced to one lane for several days. Four westbound lane reductions are scheduled so far. Two will be about a mile west of the Preston interchange:

  • 10 a.m. Monday, April 10, to 6 p.m. Wednesday, April 12.
  • 10 a.m. Monday, April 17, to 6 p.m. Wednesday, April 19.

Another two will be about 3.5 miles west of the Preston interchange will take place in June. Dates have yet to be announced.

The other four lane reductions – each requiring three to four days – are part of a separate project to repair potholes and rough roadways on several highways across King, Snohomish and Skagit counties. The I-90 lane reductions are tentatively scheduled for May and June. These will take place westbound just east of Highlands Drive Northeast in Issaquah and eastbound about a mile east of the Preston interchange.

During the closures, contractor crews working for the Washington State Department of Transportation will repair worn bridge decks and a section of westbound I-90 approaching a bridge. The closures are necessary to provide a safe work zone for the people completing the work.

“We expect similar backups to occur again this year, particularly during the morning commute hours, and appreciate drivers’ patience as we complete this work,” said WSDOT Traffic Engineer Mike Swires. “If possible, drivers should choose alternatives like working at a remote location or avoiding travel during peak traffic hours.”

People who are traveling can get real-time traffic information on mobile phones with the WSDOT traffic app and by following the WSDOT traffic Twitter feed.

Slow down on ice and snow.

It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.

Carry chains, practice installing them.

Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.

Pack your winter car kit.

Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
