State Route 20 is the northernmost route across the Cascade Mountain Range in Washington and is commonly referred to as the North Cascades Highway. This Scenic Byway offers travelers a wide array of beautiful vistas and is part of the Cascade Loop, a 400-mile driving tour through the Cascades. Take a virtual drive on the highway from your computer.

Pass status: Closed 

Apr. 17 - By the end of week three, the West side clearing has progressed to MP 154, about three miles from Rainy Pass.
The East side crew progressed through the first of the three giant Liberty Bell Mountain avalanche chutes to LB 2 at MP 163, about a half-mile below Washington Pass.
  
In recent comparable snow years, it has taken about 6 weeks to reopen , so the estimate remains mid-May.

Why we close the road
We close the North Cascades when weather, snow conditions and avalanche danger threaten the safety of drivers and our maintenance crews.  We close the highway on the west side at milepost 134, east of Diablo, and on the east side at milepost 171, 14 miles west of Mazama.  As the snow gets too deep for the plow truck, the east closure point is moved 7 miles down to the Early Winters Information Center at milepost 178. Avalanches typically close the highway between late November and mid December. 
Reopening in the spring is usually accomplished by early May.

Current driving conditions 
Between April and November when the road is typically open, we post the current North Cascades Pass report on our WSDOT mountain passes Web page as we do for all of the passes.  May through October, pass conditions are only posted if there's a potential travel hazard. 

Current weather conditions
For recreation purposes and while the highway is closed, or in the summer when the pass reports are suspended, you can find weather information with these links:
