VIEW SNOQUALMIE PASS CAMERAS →Snoqualmie Pass on Interstate 90 is Washington State's lowest-elevation year-round east-west Cascade Range crossing — 3,022 feet (921 meters) at the summit. Per Wikipedia's Snoqualmie Pass entry, the pass has the lowest elevation of the three east-west mountain routes across Washington State that are kept open year-round (alongside Stevens Pass on US-2 to the north and White Pass on US-12 to the south). Snoqualmie serves as the primary freight and passenger corridor between Seattle and Eastern Washington, plus direct access to Summit at Snoqualmie ski resort. I-90 closures at Snoqualmie typically involve the stretch between milepost 47 (west of the summit) and milepost 71 (Easton). WSDOT and WSDOT Travel operate extensive pass-area camera coverage.

VIEW SNOQUALMIE CAMERAS →Major Events Affecting Snoqualmie Pass Traffic
- Ski season weekends (November-April) — peak Friday afternoon eastbound, Sunday afternoon westbound
- Stevens Pass (US-2) closures — when Stevens closes, I-90 Snoqualmie absorbs displaced traffic
- Seattle Seahawks / Mariners away games — occasional eastbound compound when fans travel to Eastern WA for events
- Major Pacific storm events — Pineapple Express weather patterns produce multi-foot snowfalls triggering closures
Pro Tip: Snoqualmie Is Lower But Not Always Faster
While Snoqualmie is the lowest-elevation year-round Cascade crossing at 3,022 ft, Stevens Pass (US-2) at 4,061 ft and White Pass (US-12) at 4,500 ft are both alternative routes for Eastern Washington access. During I-90 closures, WSDOT sometimes reroutes traffic to Stevens Pass — which has its own winter hazards and avalanche closure risk. Check TrafficVision cameras on all three passes during major storm events.
