MAZAMA,WA.-Heavy snow over the past few days means it’s that time of year again: The SR 20 North Cascades Highway will close for the season at 4 p.m. today (Wed) Nov. 28.
The highway closes between milepost 134 near Diablo and milepost 171 near Mazama. It will reopen sometime in the spring.
Two of the four giant Liberty Bell Mountain avalanche chutes filled up over the weekend, and several of the Cutthroat Ridge chutes also filled and released snow to the highway shoulder. With more snow in the forecast, the decision was made for crews to close the highway for everyone’s safety.
