A fast-moving wildfire near Jackson, Wyo.,  closed a section of the main north-south highway through Grand Teton National Park for about three hours Sunday night and prompted the evacuation of up to 300 people from a campground, according to the Associated Press.
The fire in the northwest corner of the state had spread to about 500 acres by nightfall, but no one was injured and no structures were threatened, park spokeswoman Joan Anzelmo said.
The Gros Ventre campground was expected to remain closed at least until Monday as firefighters used the access road as a staging area.
Anzelmo said the campground evacuation was precautionary and the 200 to 300 people who were there were allowed to take their tents, trailers and other gear with them.
A 10-mile section of U.S. 89 near Jackson at the south end of the park was closed because of the proximity of the fire. It reopened at 8:30 p.m.
The entrance to Jackson Hole Airport was within the closed section, but the fire didn’t affect flights, airport security officer Bert Smith said. “Planes have been coming and going all right,” he said. “Cars have been kind of tied up, but they just opened the highway, so there’s no problem.”
