"This is bad," says an unknown voice on the video. That seems to be an understatement, as 800 cubic yards of hillside slide down onto the roadway south of Bonners Ferry.
The slide was caught on video by Idaho Transportation Department workers on April 7.
Here's what happened: ITD Land Surveyor Mathew Wilson was checking out the stability of the hillside. As he videotaped, he heard popping and cracking coming from the site. Flaggers on the scene stopped traffic as horrified workers watched. Three minutes later, the hill slowly slides right down onto the road.
