Due to concerns for public safety arising from the increased activity on the Alum Fire in Yellowstone National Park, a portion of the Grand Loop Road through Hayden Valley has been temporarily closed. That closure involves a seven and a half mile section of road from Fishing Bridge Junction north to the Elk Antler Creek pull-out. However, during this temporary closure, all travel between Canyon Junction and the Fishing Bridge requires a long detour through Old Faithful. All other roads in Yellowstone are open, as are all park entrances, lodging, stores, campgrounds and other visitor services. The Alum Fire is now estimated to involve about 4500 acres.
