Winneshiek County seeks to evaluate the potential impacts of the frac sand mining industry on its secondary roads and bridges. Of particular interest is the effect of truck traffic on roads and bridges in areas of potential mining or along transport routes. To estimate the impacts and maintenance costs of the potential routes, transportation engineering faculty and students reviewed literature on similar case studies, evaluated the properties of the materials of pavement materials, and used design software to analyze the impacts of increased truck traffic. Based on the results of their research, the class recommended three options for maintaining transportation infrastructure in Winneshiek County.
