Abstract: Drifting snow and sand on state highways has been a problem for travelers and state workers for as long as there have been roads. This presentation will describe an experiment underway in North Central Washington to see if the Vortex Generators can passively remove drifting snow and sand from the road. As state funds for maintenance are continually being reduced, more cost effective ways are needed to keep certain sections of highways safe and open during Inclement weather periods. Two eight-foot Generators were placed near a specific section of roadway during the winter of 1999-2000. This area receives snowdrifts that are a continuous problem. During the summer of 2000, three wings were placed at a location where sand from the dunes along the Columbia River blow sand onto the roadway causing an extreme safety hazard for motorist. This presentation is intended as an overview of the ongoing project.
