Access across Palisades Dam to the Calamity and Bear Creek areas closed to most motorized traffic Tuesday. Over the past summer, the new Palisades Bridge was completed by the Bureau of Reclamation just downstream from the dam, and then they built the access road from the Riverside Park campground to the Snake River and from the bridge to Bear Creek Road to provide access to the Calamity and Bear Creek areas that way. With construction work completed, winter access across the dam will be closed permanently except for snow machines and trail grooming equipment. Forest Service road access is usually closed at this time of year, but the warm fall season has delayed significant snow accumulations. However, officials caution that the new road is wet and muddy and users should expect the poor road conditions to continue until the road bed becomes snow covered or frozen.
