Final repairs will begin next week to US-95 near Rock Creek north of Bonners Ferry to address the failing slope, depending on weather and the completion of the contractor’s other slide repairs at milepost 498 near Naples.
Work will last through mid-October and will involve excavating material and installing drains to stabilize the area. A temporary signal will control traffic through the single-lane work zone.
Since the area first slid in April 2017, it has experienced additional rock fall, further undermining the pavement. Maintenance crews provided barriers and signage near the slide while the final fix was designed. To identify why the hillside continued to move and to what extent, ITD authorized a geotechnical investigation and monitored the movement.
