EMMETT, Idaho (AP) — Rock slides have forced the closure of an eight-mile stretch of Idaho State Highway 52 between Emmett and Horseshoe Bend. Idaho Transportation Department officials are examining a canal above the highway to see if seepage into the hillside could be causing the slides.

Meanwhile, travelers are being re-routed onto Shell Rock Road. The first slide in the area happened Saturday evening, followed by another on Sunday. Work crews have cleared the debris from the road, but ITD officials say they're still worried about the unstable slope above the highway and don't yet know when the road will reopen. Travelers may call 511 for traffic information.
