KAMIAH – The Nez Perce-Clearwater National Forest Office reported on Saturday via social media that progress is being made on Selway Road #233 slide repair, with a potential reopening for flow-through traffic by September 15.

According to the post, the contractor hired for the project, Debco, is continuing to receive materials such as soil anchors and steel mesh, which are needed to begin stabilizing the upper slope.

Excavation and erosion control projects at the top of the slide have been completed. Debco is preparing equipment for drilling and grouting operations and expects to begin the two-week process next week.

The Nez Perce-Clearwater National Forest Office’s post also explained the plans for continuation of the project in anticipation of a mid-September reopening.

“The project will use approximately 4,000 linear feet of soil and rock anchors installed with a high-strength wire mesh to prevent upper-level material from sliding. The installation will be done using the constructed bench and extend 1/3 of the way downslope to within 220 feet of the previous road elevation,” the post explained.

The slide contained 71,000 cubic yards of material, 30,000 cubic yards of which will be used as a buttress at the bottom of the slide raising the roadway approximately 16 feet. Approximately 41,000 cubic yards of material will be hauled away. Once soil nail installation is complete then full-scale removal of the slide material can begin.
