Traffic Impacts and Road Advisories

In mid-December the state of Washington experienced unprecedented flooding activity that brought rain and wind causing hazardous driving conditions, power outages, log jams against bridges, and road closures across the Cascade Loop.

Restriction information: www.co.chelan.wa.us/public-works/pages/traffic-alerts-and-restrictions

Highway 2 is closed entirely to Eastbound traffic from Skykomish to the top of Stevens Pass/Stevens Pass Ski Resort until JANUARY 4TH.

From WSDOT 12-30-25 --- BIG NEWS:

US 2 near Skykomish is expected to REOPEN by Sunday, Jan. 4, in both directions from MP 50 to MP 64 (Stevens Pass Resort).We know there's been a lot of moving parts with this one, so let's break it down from west to east:

FROM SKYKOMISH TO STEVENS PASS RESORT (MP 50-64): US 2 Will be in both directions 24/7 starting Sunday, Jan. 4. Note: Because access from the east is still limited to daylight pilot car operations, the road AT Stevens Pass (MP 64) will close nightly at 6 p.m.

FROM STEVENS PASS RESORT TO MILL CREEK ROAD (MP 64-71): US 2 is OPEN to daylight pilot car operations from 6 a.m. to 6 p.m. daily. A pilot car guides alternating one-way traffic in each direction. THIS IS AN ACTIVE WORK ZONE. Do not pass the pilot car NOR the line following the pilot car.

FROM MILL CREEK ROAD TO COLES CORNER (MP 71-85): US 2 is OPEN in both directions from 6 a.m. to 6 p.m. daily.

FROM COLES CORNER TO LEAVENWORTH (MP 85-99): US 2 at Tumwater Canyon remains CLOSED in both directions. Repairs started Dec. 23, and we expect it will remain closed through mid-March. The detour around that section is Chumstick Highway to Beaver Valley Road. Except for the Christmas Day holiday, crews have worked around the clock clearing debris and doing roadway and streambed repairs. The progress allowed inspections to take place which determined the road and bridges between Skykomish and Stevens Pass can handle limited travel. US 2 is an active work zone, so you should expect delays. US 2 is not yet the through route you're used to. Consider I-90 or US 12, when possible.

Please watch the WSDOT Traffic Map for changes and updates - https://wsdot.com/Travel/Real-time/Map/

At this time, to best route to travel from the West (Seattle area) is via I-90 (Snoqualmie Pass) and US 97 (Blewett Pass) to Leavenworth.

North Cascades Highway Update

12-2-25 --

SR 20 North Cascades Highway closed for the season Thursday, Dec. 4, 2025 at 6 p.m.

WINTHROP – State Route 20 North Cascades Highway will close for the winter season at 6 p.m. Thursday, Dec. 4.

Rainy Pass (elevation 4862 feet) and Washington Pass (elevation 5475 feet) will close between Ross Dam trailhead (milepost 134) and Silver Star gate (milepost 171). Depending on conditions, the closure points are typically moved to lower elevation closure points later in the season, moving to the Newhalem gate (milepost 120) on the west side and Early Winters gate (milepost 178) on the east side.

The Washington State Department of Transportation will close SR 20 North Cascades Highway for the winter due to conditions and avalanche risk. With current snow loads in avalanche pathways and snow showers forecast in the North Cascades beginning Friday, crews determined it is time to close for the safety of the traveling public and crews.

The earliest closing date for the North Cascades Highway was Oct. 17, 2007. The latest seasonal closure date was Jan. 3, 1990.

Don’t guess and check for updates.

We are often asked why we don’t set a specific date for the closure. The reason is that every season is different and we want to remain open as long as possible each year. Closing dates have been as early as Oct. 17 and as late as Jan 3. Our crews work hard to keep the North Cross open because this route provides more direct access for freight and the communities on each side of the mountains.

As soon as the team determines the route must close, we share that information through this listserv, Facebook, and the mountain pass page.

If you are planning on making the trip over the “North Cross”, remember that you are traveling through mountain passes with no cell service and with snow forecast for this weekend. You must be prepared for winter driving. Have appropriate tires and drive for conditions. Understand that you can be prepared and still get stuck waiting because of a collision or spin out somewhere else on the mountain pass, so have a full tank of gas and something warm to bundle up in if you have to wait. Our crews are plowing and treating the roads, but as we often see at the beginning of winter, some people aren’t prepared and make the situation even more challenging.

Keep travel lanes and driveways open

Last weekend, plow drivers reported that people were parked on the side of the road, into the driving lanes and in some places, blocking access for crews to get around. This not only hinders plow drivers’ ability to clear the road, but it is also a safety hazard for traffic and first responders. Please be responsible and park only where allowed.

The Washington State Department of Transportation (WSDOT) does an amazing job of keeping our roadways safe and well-maintained. They also are an essential partner in keeping us and our travelers informed about any accidents, closures, or other issues that can impact the normal flow of traffic.

Wildfire and Smoke Safety

Summer season often brings news of wildland and forest fires in the high country near the Cascade Loop. Very rarely travel is impacted by these fires, but occasionally a highway closure or flagger controlled traffic revisions are put in place to assure safe travel.

If fires near the roadway threaten travel, we will post alerts on social media and on this page (find it easily as a 'Travel Alert' bar at the top of every page)

To follow fire activity, these public links are updated by the appropriate agencies regularly:
