Postponement of Planned Road Closure until 2015: A planned closure of the Cascade River Road during September and October in order to perform permanent repairs at the Boston Creek crossing, 1.2 miles from the Cascade Pass trailhead has been delayed until 2015. The Boston Creek crossing has been repeatedly damaged and closed, most recently in August 2013, when over 100 visitors were stranded after a storm caused a sudden road washout. Press Release
