Use of Snow Fences to Reduce the Impacts of Snowdrifts on Highways: Renewed Perspective

In northern climates, snow fences are usually established in or beyond the right-of-way to eliminate blowing and drifting snow on roadways and thus improve road safety. To make snow fences more effective on highways and provide guidelines for the departments of transportation siting the fences, this work reviews the literature as well as survey responses from practitioners in northern states. This review combines information obtained from the resources to detail several aspects of snow fence use, including history, design protocols, siting policies, benefits, challenges, and numerical modeling. Particular attention is paid to living snow fences as an alternative to traditional structural snow fences. The survey results show that almost all the responding agencies have launched snow fence programs, which have various design and siting protocols that depend on the specific conditions.
