I-90

Evening work planned at different sites from March through June

SHORELINE – A project to update and improve the safety of 24 guardrails and barriers across King, Snohomish and Whatcom counties begins mid-March, adding energy-absorbing features to reduce the impacts of crashes.

ISSAQUAH – People who use State Route 18 between Snoqualmie Pass and south King County will want to plan for alternative routes and extra travel time Friday, Dec. 15. Beginning at 4 a.m. until 2 p.m., the highway will close from Interstate 90 to Issaquah-Hobart Road Southeast for emergency asphalt repairs

During the closure, Washington State Department of Transportation maintenance crews will remove and repave damaged asphalt.

BELLEVUE – A long-term shift of the eastbound Interstate 90 lanes in Bellevue begins later this month, marking the onset of major construction for the nearly 3.5-year I-90 Sunset Creek fish passage project.

Beginning at 4 a.m. Wednesday, Aug. 23, the eastbound lanes will jog to the left and into the newly paved median between the I-405 interchange and 148th Avenue Southeast. Travelers will also encounter a rolling slowdown between 12:01 and 4 a.m. while crews paint new lines on the freeway.

Lower speeds through late 2024 will support safety near construction zones

SNOQUALMIE – Construction along State Route 18 near Tiger Mountain has slowed traffic through the area since it began. With temporary speed limit reductions on the way next week, travelers should plan now for a little additional time for their trips through the end of next year.

The Washington State Department of Transportation has many projects scheduled during the summer construction season, including:
