From the Washington State Department of Transportation:
Avalanche risk closes SR 20 North Cascades Highway
BURLINGTON – The North Cascades Highway section of State Route 20 is now closed until next spring.
The Washington State Department of Transportation has been monitoring the road and the avalanche chutes above the highway. WSDOT maintenance and avalanche technicians temporarily closed the highway Friday, Nov. 18, due to weekend snow forecasts.
Conditions were re-evaluated today, Monday Nov. 21, and more avalanche chutes are full and not stable – especially near Liberty Bell Mountain area – causing crews to close the road for the season.
“While there hasn’t been a ton of snow on the road, it’s continued building at higher elevations in the chutes,” said Twisp Maintenance Supervisor Don Becker. “The potential avalanche risk makes reopening unsafe for our crews and drivers.”
It re-opens in Spring - a gorgeous stretch of road but treacherous in winter.
