6 The report will help federal, state, and local transportation managers and agencies better understand and communicate the energy development impacts on roads and bridges, and select the appropriate strategies for managing them. Other aspects of the impacts of energy development on roadway infrastructure that are explored in this study include: • Areas of the country where road infrastructure damage from energy development are an issue for state and local transportation agencies; • Types of development associated with infrastructure damage; • Economic costs associated with supporting energy development companies with adequate and sustained infrastructure; • Current design standards (or amended standards, if any)

7 Interviews of Transportation Practitioners in Focus States Based on the results of the survey and literature review, five states were selected for additional data gathering on practices used related to managing the impacts of energy development. A number of criteria were considered in selecting the five focus states to be interviewed.
