RAINY PASS - Mud and rock slides have closed a section of the North Cascades Highway through the mountain passes, with no reopening date yet announced.
Heavy rain Thursday night, Sept. 5, into Friday triggered several slides, closing a 24-mile stretch of Highway 20 between milepost 147 (10 miles west of Rainy Pass) and milepost 171 (9 miles east of Washington Pass).
Washington State Department of Transportation crews are waiting until the rain subsides to begin cleanup efforts, because more slides are possible.
Once crews can assess how much needs to be cleaned up, they will give an estimate for reopening the area. That estimate isn't expected until next week.
Slides Aug. 10 and 11 closed much of the same section of Highway 20 for several days before they could be cleared.
