Wildfires in Idaho: Highway 55 fire grows to 3,500 acres; 423 battling fire near Riggins

A wildfire that started Wednesday afternoon near Idaho Highway 55 north of Horseshoe Bend has now burned 3,000 to 3,500 acres, according to the Idaho Department of Lands.

The fire damaged power poles, and Garden Valley was without power Thursday while crews worked to replace those. Power was expected to be restored late Thursday night.

One lane of the highway is open with single-lane traffic alternating with a pilot car, but motorists should expect long delays and be prepared to encounter falling rock.

Officials urge travelers to avoid Idaho 55, if possible. Travelers going to McCall are asked to take U.S. Highway 95, while those headed to Stanley are asked to take Idaho Highway 21 or go through Sun Valley.

The cause of the Mile Marker 73-Highway 55 Fire is under investigation.

Resources on the fire: one helicopter, three single-engine air tankers, one very large air tanker, and multiple engines. Garden Valley and Horseshoe Bend Rural Fire Departments are on scene. Two dozers and two additional crews were ordered and expected to arrive Thursday.
