MOUNT VERNON, Wash. (AP) — The North Cascades Highway in Washington state opened to vehicle traffic at 10 a.m. Tuesday, officials said.

“The SR (State Route) 20 North Cascades Highway is open for the season! Huge thanks to our crews for their hard work!,” the state Department of Transportation posted on Twitter.

Transportation officials said in a news release that workers for the past six weeks have been clearing the highway of snow between winter closure points near Diablo and Mazama.

Last week, crews clearing snow from the east and west sides of the North Cascades met just west of Rainy pass.

The highway has been closed between the closure points since Nov. 15.

Officials said avalanche potential remains, and many Forest Service and Parks Service facilities in the area remain closed.
