Economic Impact Study of Completing the Appalachian Development Highway System

The Appalachian Regional Commission (ARC) has commissioned this economic impact study to estimate the economic impacts, benefits, and costs of completing the Appalachian Development Highway System (ADHS). The ADHS is the first highway system authorized by Congress for the purpose of stimulating economic development. The ADHS is a 3,571-mile near-interstate grade highway system composed of 31 corridors located in 13 Appalachian states with 3,090 eligible for improvement. The system is approximately 85 percent finished and the completion will link the whole system into an integrated network connecting to national markets and trade flows. The purpose of this study is to assess the travel performance, trade, and economic development impacts directly related to completing the ADHS. In addition, the study assesses connectivity, accessibility, and network effects – in other words, how do the corridor improvements connect Appalachian people and businesses to other highway facilities, multimodal transportation, and economic markets (labor force, buyers/suppliers, tourists). The study has produced estimates of near- and long-term travel and economic benefits, including benefit/cost analysis to evaluate the expected economic return on investment of completing the ADHS to both the ARC region and the U.S. Furthermore, three regional case studies have been completed in the north, central and south sections of the ARC Region to provide detailed information for calibrating the modeling assumptions based on structured interviews with key transportation users and economic development experts.
