Washington road conditions right now

Every closure and crash WSDOT is publishing, on one map with the route and mile marker. Below it: the live cameras, Snoqualmie Pass, Stevens Pass and Crystal Mountain (SR-410), the I-5 and I-90 corridor pages, and what the season does to Washington's highways. For the whole country, see the US closures map.

Report

Labor Day 2026 in Washington

What the WSDOT feed carried over the holiday weekend.

Driving across Washington

I-5 runs the length of the state, about 276 miles from the Oregon border through Vancouver, Olympia, Tacoma and Seattle up to the Canadian border. I-90 crosses from Seattle east over Snoqualmie Pass toward the Idaho line, nearly 300 miles. I-405 is the Eastside bypass around Lake Washington through Bellevue and Renton. US-2 climbs over Stevens Pass, US-97 runs north to south east of the Cascades, and US-101 loops the Olympic Peninsula.

What the season does to Washington's highways

Washington closes highways more than most states. Snoqualmie Pass, around mile marker 52 on I-90, and Stevens Pass on US-2 shut for hours during winter storms and avalanche control. SR-20, the North Cascades Highway, closes across a long stretch every winter and reopens in spring, and Chinook and Cayuse passes close seasonally too. WSDOT posts chain requirements for each direction and every closure by milepost.

Before a Washington road trip

Check the map above for anything red on your route, then open WSDOT for the DOT's own detour and restriction text.
Look at the road. The Washington cameras show the pavement itself, and most carry the mile marker.
If the route crosses Snoqualmie Pass, Stevens Pass and Crystal Mountain (SR-410), read the pass page for the summit cameras, snow depth and chain rules.
For the long haul, the I-5 and I-90 corridor pages carry alerts for every state the route crosses, not only Washington.
Know how to say where you are. Dispatch, 911 and tow companies ask for the route, the direction and the mile marker. How to report your location on the highway.
Carry the app. The mile marker works offline in all 50 states, and the same WSDOT alerts show on your route as you drive.

What September looked like

Over 25 daily snapshots from September 1 to 25, 2026, MileCheck's archive of the WSDOT feed held 873 unique reports, including 14 closure reports, 41 crash reports and 752 work-zone reports. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the September Highway Report.

Questions, answered

Is the highway closed in Washington right now?

The map above shows every full closure WSDOT is publishing as a red marker, crashes in orange, and weather and hazard alerts in blue and purple. Closures the DOT has posted for a future date are listed as scheduled, and ramp and lane closures sit under the toggle so the list stays readable. It reloads every five minutes. If the feed cannot be reached the page says so instead of showing an empty map. For the official list, open WSDOT.

Where do I check Washington road conditions?

WSDOT is the official source, and dialing 511 in most states reaches the same information by phone. This page reads the same WSDOT feed and adds the Washington cameras, the corridor and pass pages, and your own mile marker if you carry the app.

Are chains required in Washington?

Chain and traction rules are set by WSDOT per road and per direction, and they change with the storm. Restrictions the DOT publishes as alerts appear on the map above and on the Snoqualmie Pass, Stevens Pass and Crystal Mountain (SR-410) pages. Always follow the posted signs. What "chains required" means explains the levels.

How often does this page update?

Every five minutes. MileCheck's server fetches the WSDOT feed, converts it to one format shared by all 50 states, and caches it for five minutes. Each alert also carries the time the DOT last updated it, shown in the list.

Does the MileCheck app show these alerts?

Yes. The app shows the same WSDOT alerts on your route, ahead of your position, with the mile marker you are passing. The mile marker works offline in all 50 states. Live alerts are part of MileCheck Premium, $49.99 a year or $9.99 a month after a 7-day free trial.

Know exactly where you are — live

Your mile marker shows even offline. WSDOT alerts on your route and the nearest camera are part of MileCheck Premium and need a connection to update. Runs on CarPlay and Android Auto.
