STATES INTENSIFYING EFFORTS TO REDUCE HIGHWAY LANDSLIDES

A recent survey by the Federal Highway Administration (FHA) shows the U.S. is presently spending $50,000,000/yr to repair major landslides on the Federal-aid highway system. The total cost of all landslides on all U.S. highways is at least $100,000,000. Most of these landslides could have been avoided had a preliminary soils investigation been made before routing the highway. Water is either the controlling factor or a primary contributing factor in 95% of all cases. Accordingly, drainage is the most effective means for preventing and/or controlling landslides. The most common correction methods are (1) Slope flattening and drainage; (2) Buttress with drainage; and (3) removal and replacement.
