Recent rains have caused a significant washout on the Mid-Fork Snoqualmie Road in the Cascade foothills. The area is a popular destination for off-season day-hikers, and the washout adds significant mileage to hikes here. According to Bill Sobieralski, wilderness and trails coordinator for the Snoqualmie Ranger District, an impassable slump has occurred in the Mid-Fork road at milepost 6, just beyond a concrete bridge over the river. The washout is about 6 miles short of the Mid-Fork trailhead, so hikers should plan to add an additional 6 miles one-way to any hike accessed by the road.
King County has jurisdiction over this portion of the road, and according to road maintenance superintendent Tony Ledbetter, the slump is about 6 to 8 feet deep and covers out about a 100-foot stretch of road. Barricades are currently in place and the road is closed to traffic beyond the washout. A four-foot shoulder is available for hikers to walk around the damage, but cars are prohibited from passing.
Ledbetter indicated that crews have been drilling soil samples to investigate the cause of the washout, "so that we're not just putting a Band-Aid fix on the road," he said. He estimated repair work could begin in about 2 weeks.
The washout comes as the Forest Service is reviewing plans to gate and decommission the Mid-Fork road beyond the Dingford Creek crossing. For more information, contact the Snoqualmie Ranger District at (425) 888-1421.
