Two ramps at Interstate 90 and State Route 18 interchange will close overnight Tuesday and Wednesday nights, Oct. 1-2, near Snoqualmie. A lane on a third ramp will close early Thursday, Oct. 3.
Contractors working for the Washington State Department of Transportation will use the closures to install barriers, add striping along the ramps and stabilize slopes with seed and compost as part of the I-90/SR 18 Interchange Improvements project.
