Traffic Impacts and Road Advisories
Please be aware of several closures and detours this fall while necessary roadwork will take place to improve the safety and experience for visitors:
================
Trailhead parking areas close in the North Cascades
The Okanogan-Wenatchee National Forest has temporarily closed several trailhead parking areas along Highway 20 near Washington and Rainy passes. The closures will be in place during parking lot and entry road repairs, pavement replacement and the repainting of parking lot stripes. Alternative parking near the trailheads is limited or nonexistent, and restrooms will be closed while the work is being done.
Washington Pass Overlook and the Bridge Creek Trailhead will be closed until Sept. 7.
The Rainy Pass Picnic Area (Heather and Maple Pass Trail) and Rainy Pass North Trailhead are closed until Sept. 25.
While trails will not be closed, access will be affected and in some instances unavailable.
Rainy Lake Trail No. 310, Heather Maple Pass Trail No. 740 and Lake Ann Trail No. 740.1 will have no ADA or general access during paving. Vegetation is dense along the edge of the trailhead, the area is extremely marshy and hikers are asked to choose other areas in which to recreate.
Through-hikers on PCT trail No. 2000 will be able to continue through the Rainy Pass area. There will be a detour to allow hikers to avoid the paving areas.

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:
