GSMNP (press release) Great Smoky Mountains National Park officials announced the temporary closure of the Cosby entrance road due to flood damage. Recently flash flooding along Rock Creek spilled over the banks damaging road shoulders along 1,500 linear feet of the Cosby entrance road. Underground electric and phone lines were exposed along most of the road where the shoulder area was washed out up to 6 feet deep. All electric power and water service to the campground and picnic area has been shut off.
Park maintenance crews cleared rocks and debris from the roadway and coned off washed-out road areas to allow one-lane traffic to escort campers from the campground this morning. The campground, picnic area, and all roadways will remain closed until power and water services can be restored and the repairs are complete. Park crews are further assessing the condition of the road today and will begin making repairs immediately.
Trails remain open at this time, but there is no trailhead access. Hikers are advised to use caution throughout the area. Crews are currently assessing the area for any damage to trails and footlogs. Roads are closed to all pedestrian traffic in the area throughout the closure.
