MAMZA, Wash. - The North Cascades Highway/SR 20 reopened Thursday afternoon west of Granite Creek after crews cleared a "massive" mudslide.
According to Washington State Department of Transportation, SR 20 had been closed between the Ross Dam and just close to Mazama.
Washington State Patrol Trooper Jacob Kennett said the weather caused mudslides and part of the roadway to be washed out.
The fallen trees and land blocked both lanes of the road.
Kennett tweeted: "Until further notice, State Route 20 pass will be closed across the mountains."
SR 20's closure comes as Stevens Pass/US 2 shut down due to wildfires, making pass and cross-state travel difficult.
