BENEFITS AND COSTS OF SNOW FENCES ON WYOMING INTERSTATE 80

Snow-fence protection along a 100-km section of Wyoming Interstate 80 has gradually been increased from none to 50 percent since 1970. This presents a unique opportunity to identify effects of the snow fences on snow-removal expenditues, accident frequency, and road closure. This information is needed for economic analyses to determine the feasibility of future snow-control projects. The study indicated that snow-removal costs were reduced by more than one-third as a result of the effective elimination of snowdrifts. Accidents during blowing snow conditions decreased in proportion to the length of highway protected, with a 70 percent reduction at the current level of fencing. There is some indication of a comparable reduction in wind-related accidents. These effects reflect the improved visibility and road-surface conditions observed in the areas protected by snow fences. The fences have had no significant effect on the length of time the highway is closed to traffic, and it is hypothesized that protection might have to approach 100 percent before such an effect could be expected. Fence construction costs can be amortized within 10 years through reduced winter maintenance costs and property damage. Effectiveness of the snow fences is attributed primarily to adequate snow-storage capacity and the use of tall (3.78-m) fences. (Author)
