State Route 503, also known as Lewis River Road, closed on Monday, March 13, when a debris slide knocked trees and rocks down onto the highway near Speelyai Bay Road, about 21 miles east of Woodland in Cowlitz County. [WA Department of Transportation is] putting an emergency contract in place with Pacific Blasting to remove the slab and stabilize the hillside as soon as safely possible. While the debris on SR 503 may not look like much, it’s the instability of the slope above, including a massive rock slab, that has kept the highway closed. You can sign up to receive email alerts with updates about the work to stabilize the hillside and news about when the highway will reopen.

January 29, 2017 update

Road to Climber's Bivouac is closed due to accumulating snow.  The winter climbing route (worm flows) out of Marble Mountain Sno-Park is now the preferred climbing route until spring. However, FR 83 is only open to Cougar Sno-Park at the current time. 

The snow level is currently at right around 1,500'. Be prepared for cold, wet, winter conditions by having appropriate winter climbing gear and strong winter navigational/orienteering/mountaineering skills.

See the U.S. Forest Service Mount St. Helens National Volcanic Monument website for more information.
