A Review of Denali Highway Lifecycle Costs

The Alaska Department of Transportation and Public Facilities (DOT/PF) has considered several alternatives for maintaining the Denali Highway. The Alaska Center for the Environment asked the Institute of Social and Economic Research (ISER) to review published estimates of the cost of maintaining the road to see if they are consistent with standard economic methodology. To conduct this review we relied primarily on two DOT/PF memorandums and a spreadsheet. DOT/PF confined that these documents are the most recent estimates of several relevant publications listed at the end of this report....We supplemented this information with several relevant publications listed at the end of this report. The remainder of this report summarizes our review of maintenance and construction costs of the Denali Highway. We describe the data used in the study, present the primary findings, describe the sensitivity of results to changes in assumptions, suggest future areas of research, and make final recommendations.The Alaska Center for the Environmen
