A portion of the North Cascades Highway that is normally accessible for winter sports will be closed for a month after a large rockslide covered the roadway.
The slide covered about 300 feet of Highway 20, the North Cascades Highway, east of milepost 142, near the Whatcom-Skagit County line, the Washington State Department of Transportation said Wednesday.
The roadway, which is already closed to vehicle traffic for the season, will be closed to winter sports — cross-country skiing, snowshoeing and snowmobiles — for about a month starting Jan. 5, between mileposts 134, near the Ross Dam trailhead, and milepost 143.
The roadway is closes each winter to vehicle traffic because of heavy snow and avalanche danger, the transportation department said. Though the slide is east of where the gate is closed for the winter, the slide needs to be cleared now in order to reopen the highway on time next spring.
The transportation department said the road will again be available to cross-country skiers, snowshoers and snowmobiles once the slide is cleared.
