The Appalachian Development Highway System (ADHS) is a network of highways designed to improve transportation and economic development in the Appalachian region of the United States. Established in 1965, the system aims to connect rural areas to urban centers, enhancing access to jobs, education, and healthcare. The ADHS consists of over 3,000 miles of highways across 13 states, including West Virginia, Kentucky, and Tennessee. This infrastructure project not only facilitates travel but also promotes regional growth by attracting businesses and tourism, ultimately improving the quality of life for residents in the Appalachian region.
