Map of the Appalachian Development Highway System

The Appalachian Development Highway System (ADHS) is part of the Appalachian Regional Commission in the United States.

History

1966 map

The PARC report and the Appalachian governors placed top priority on a modern highway system as the key to economic development. As a result, Congress authorized the construction of the Appalachian Development Highway System (ADHS) in the Appalachian Development Act of 1965. The ADHS was designed to generate economic development in previously isolated areas, supplement the interstate system, and provide access to areas within the Region as well as to markets in the rest of the nation. The system has served its intended purpose to varying degrees of success.

Currently, the ADHS is authorized at 3,090 miles, including 65 miles added in January 2004 by Public Law 108-199. By the end of FY 2004, 2,627 miles?approximately 85 percent of the 3,090 miles authorized?were complete or under construction. Many of the remaining miles will be among the most expensive to build.

Corridor Z across southern Georgia is not part of the official system, but has been assigned by the Georgia Department of Transportation.
