Is the North Cascades Highway open?
Updated August 19, 2026 · Pictures refresh every few minutes
Only WSDOT can say — and SR-20 closes every winter. The official WSDOT North Cascades Highway page has today's status and the seasonal gate dates. That page remains the final authority.
Then look at the east-side cameras below — knowing they are not the summit.
When does it open and close for the season?
There is no fixed date. WSDOT usually closes SR-20 between the avalanche gates in late fall and reopens it in spring, but the exact dates change every year with the snowpack and avalanche danger. The WSDOT page announces both the closure and the reopening — do not plan a Washington Pass drive off last year's dates.
Which cameras can I actually check?
Honest answer: there is no camera at Washington Pass or Rainy Pass — WSDOT publishes none anywhere on the high stretch. The National Park Service runs one at Newhalem, on the west approach, and the nearest road stills are on the east side at Winthrop and Loup Loup. None of them shows the summit.

Official National Park Service and WSDOT stills. Check the time printed on the picture. Snow in Winthrop does not tell you what Washington Pass looks like — and clear skies in Winthrop do not either.
Why can the highway be closed on a sunny day?
The winter closure is about avalanche danger on the slopes above the road, not the weather at the moment you look. WSDOT also closes SR-20 mid-season for slides, rock fall, and fires. A blue-sky picture in the valley does not reopen a gated highway. The posted status always wins.
What is the detour when SR-20 is closed?
Cross on US-2 over Stevens Pass or I-90 over Snoqualmie Pass, then come north on the east side. Compare Stevens and SR-20 before you pick.

The SR-20 traffic desk keeps the WSDOT status link and the east-side cameras in one place.
