On the afternoon of 14 January 2008, a mid-sized excavator was being loaded onto a barge as part of the Idaho Transportation Department (ITD) Harrison Bridge construction project. The State Highway 97 bridge project is located near Harrison, Idaho. One of several barge mooring lines gave way causing the barge to move before the excavator had been secured. The excavator slid off the barge into the Coeur d'Alene River. The effected river segment is found within the Coeur d'Alene Basin Superfund Site.

The recovery plan was implemented on the morning of 18 January 2008 without incident.
