A portion of Idaho 55 was closed Sunday afternoon due to a grass fire, according to the Idaho Transportation Department.
Around 5:30 p.m., Eagle Fire Department officials said the fire was 90 percent contained and projected that the road would reopen by 6:30 p.m.
According to officials, the fire appears to have been started by a truck with "mechanical issues," though an investigation is still pending.
The fire was first reported shortly near the Avimor housing subdivision after 1:45 p.m. The highway was closed between Floating Feather Road and Horseshoe Bend Hill Summit (mileposts 46 and 52) shortly afterward.
Thanks to an "aggressive attack" by Eagle Fire, Star Fire, Boise Fire, Bureau of Land Management and the U.S. Forest Service, the fire burned only about 250 acres. No one was injured, and no structures were threatened, officials said.
