CONTROLLING UNSTABLE
HIGHWAY SLOPES
Idaho's roadways traverse through some of the most beautiful landscapes in the country.
Spectacular vistas, wild and scenic rivers, and majestic mountain sides make driving in
the state a visual pleasure. Constructing roadways in such rugged areas is a remarkable
engineering feat; maintaining them to assure the safety of motorists is an ongoing
concern for the Idaho Transportation Department (ITD).
When steep slopes along roadways are unstable, rocks, soil and other debris can fall
onto the highway causing detours, traffic delays and dangerous driving conditions. In
the late 1990s, ITD recognized the need to evaluate slope instabilities and to prioritize the
sites needing maintenance or stabilization. Although some rockfall problem areas were
well known in the state, the severity and extent of these problems could not be well
established because a comprehensive inventory had not been completed for Idaho
