A section of Idaho 52 shut down by two rockslides over the weekend has been reopened to traffic, according to the Idaho Transportation Department.
Traffic will be flagged through the one open lane in an alternating pattern for about a quarter of a mile.
Officials suspect the falling debris, which affected the highway between Emmett and Horseshoe Bend, was caused by leaking from a nearby canal.
The canal, a spring, or some other water source had saturated the hillside above the highway, making it unstable, ITD personnel said.
Experts will inspect the canal Tuesday to see if it is the source of the moisture. Traffic on Idaho 52 will remain restricted until the route is deemed safe.
The rockslides occurred Saturday evening and Sunday afternoon. The debris was cleared from the road, but officials closed the highway at 1 p.m. Sunday out of concerns that more rocks may fall onto the road.
Traffic had been routed to Shell Rock Road. Drivers planning to travel on Idaho 52 can call 511 or check 511.idaho.gov for the latest information.
