The Stekekin Valley road is washed out at mp 9.5 anyway.
"No National Park Service shuttle service due to road damage: The Stehekin Valley Road from High Bridge to Glory, where the National Park Service usually provides shuttle service in the summer, was severely damaged and will not be available for use in 2004. Therefore, there will be no shuttle service above High Bridge. At this writing (May 11) the Stehekin River continues to occupy a stretch of the Stehekin Valley Road a half mile above the Stehekin River Ranch. The National Park Service anticipates that a private permittee will again provide bus service from Stehekin Landing 9.5 miles to this point. The Bullion Loop Trail and the Old Wagon Road Trail (Pacific Crest Trail) provides hikers and horseback riders with a route around a significant portion of the damaged road. (Bicyclists may use the Bullion Loop Trail to bypass the flooded road section as far as Bullion Camp, where they can rejoin the road. Please note that all other trails in the North Cascades National Park Service Complex are closed to bicycles as well as to motorized vehicles.)"
