Idaho Transportation Department officials estimate that it could be Saturday afternoon before crews are able to clear all the debris from a section of Idaho 55.
A Thursday evening mudslide swept soil and rocks over the roadway. ITD had originally hoped to have the roads open by Friday.
The closure stretches from Garden Valley Road to Smiths Ferry Drive. The Banks to Lowman Road had been closed from Highway 55 to Garden Valley, but was reopen as of Friday night.
The mudslide happened at about 7 p.m. after heavy rains fell in an area that had previously burned in a wildfire, according to the Idaho Transportation Department. The water swept loose soil and other debris down the hillside and over the road.
Crews are working to remove the debris so the road can be reopened. Drivers are advised to use U.S. Highway 95 as an alternate route.
Travelers can call 511 or visit 511.idaho.gov for the latest road conditions.
