North Cascades Highway rock slide 6/10/2020
A series of rock slides on the night of June 10th blocked both directions of SR 20 near Rockport, leaving a pile of rocks and trees nearly 20 feet deep and 120 feet wide. A signed detour takes drivers from SR 20 to westbound SR 530 at Rockport, east on Rockport Cascade Road, west on Cascade River Road and back to SR 20 in Marblemount. Because of the slope instability, the highway remains closed at milepost 98, and will stay closed through the weekend.
