Living Snow Fences

Control blowing and drifting snow

Using road design and snow fences to control snow on roadways

Drift-free roads are achievable through two mitigation strategies: proper road design and/or the use of snow fences. A suitably designed roadway will promote snow deposition in ditches rather than on the roadway, and blowing snow that does reach the road will move across without drifting. Snow fences can also help maintain clear roadways by capturing blowing snow upwind of a problem area and storing that snow over the winter season.

Snow climatology

The topography, land-use characteristics and winter climate for much of Minnesota cause this area to be particularly vulnerable to blowing and drifting snow on roadways. The end result of the problem often includes a reduction in driver safety, degradation of road quality, and significant removal costs for drifted snow.
