One lane of Idaho 55 north of Horseshoe Bend reopened at 1 p.m. on Wednesday with pilot cars guiding vehicles, the Idaho Transportation Department announced.
Northbound and southbound vehicles, guided by the pilot cars, will take turns driving on the section of Idaho 55 that is north of Horseshoe Bend and just south of the Banks to Lowinan route, which is Idaho 17.
Both lanes in that section of Idaho 55 closed Tuesday at about 12:30p.m. because of the Chief Parrish Fire, which is burning close to the highway.
Rolling debris and falling trees were reported across the highway on Tuesday.
The fire started at about 5 p.m. Monday evening. It had burned at least 2,500 acres as of Wednesday at noon.
No time had been set to reopen both lanes of Idaho 55.
