But the length of the Wednesday closure, starting at 7 p.m., will depend on the amount of time it takes to remove boulders and large pieces of debris. Crews will also evaluate and repair any damage to the highway. Drivers need to plan for up to four hours of additional travel time.
Also, crews are repairing bridge decks along I-90 between Easton and Ellensburg. Construction starts April 29, and you can expect single-lane closures during the day.
