One westbound lane of Interstate 90 over Snoqualmie Pass will remain closed until later tonight while crews work to clear a rockslide, according to the state Department of Transportation.
The slide, which occurred about 5 p.m. Tuesday, sent a 12-by-6-foot boulder along the highway.
Crews are breaking the gigantic boulder into smaller pieces and removing it from the highway. They are also working to remove debris from the ditch and restore water drainage along I-90.
Drivers heading west from milepost 70 to milepost 54 may encounter minor delays due to the single lane closure, WSDOT reports.
