Abstract: Millions of dollars are spent annually to maintain Canadian highways in order to make them safe for motorists during the winter. In Ontario, it is estimated that on average $3,000/km of highway is spent annually for winter maintenance. The majority of this money is directed towards snowplowing and sand/salt application. Since snowdrifting can significantly increase these maintenance costs, this study was undertaken to reduce the amount of drifting snow on highways. The final product of the study was a manual developed to minimize the quantity of drifting snow approaching a highway by placing devices upwind of the road such as snowfencing, landscaping or terrain modifications.
