The Washington State Department of Transportation (WSDOT) has given you fair warning. Expect lane closures around the clock next week on I-90 east of Snoqualmie Pass. A major improvement project is underway to build a wider, safer and more reliable stretch of road between Hyak and the Stampede Pass interchange.

Contractor crews with the Washington State Department of Transportation will reduce the eastbound and westbound lanes to a single lane in each direction 24 hours a day from 6 a.m. Monday, April 30 until 9 a.m. Thursday, May 3 between mileposts 56 and 60.

Drivers traveling eastbound will experience the most delay on Monday with an added travel time of an hour. Only minimal delays are expected to impact traffic in both directions Tuesday through Thursday.

The WSDOT does offer these handy tools to help you when traveling:
