The Association was a group of community leaders from towns and cities along the “Old Spanish Trial” from St. Augustine, Florida to San Diego, California. The association formed to promote the development of a motorable highway throughout the South as a spur to local development. The archives of the Association include reports and memoranda, membership books, minutes, correspondence, clippings, brochures, and books published by the Association in pursuit of its objective to facilitate tourism in their locales.
