Ethanol Production and Wind Energy: Challenging Low-Volume Roads in Iowa

Most of Iowa’s county roads have granular surfaces and were designed for farm traffic. However, the increased interest in alternative, sustainable energy sources such as ethanol and wind energy has led to dramatic changes that affect traffic patterns on Iowa’s low-volume roads. The production of ethanol from corn has placed a tremendous strain on low-volume roads for the delivery of raw materials and the shipping of finished products. The large weight and size of wind turbine components are also straining and damaging rural roads. This article summarizes these challenges and discusses how to finance the resulting road maintenance needs.
