This collection represents 68 years of materials authored or collected by Turner. Series 1. through Series 4. include highway engineering reports written for the Bureau of Public Roads, Clay Committee papers dating from the 1950s hearings on the development of a national interstate highway program, and speeches, publications, correspondence, and research notes generated by his career as a federal highway official. The aforementioned inscribed copy of A More Beautiful America by Lyndon Baines Johnson is is included in this material.
Upon his retirement, Turner became a transportation consultant, advising local, national, and international agencies, associations, and companies on transportation issues. The bulk of these post-retirement and consulting materials are found in Series 5 through Series 9. These materials include maps, photographs, research notes and manuscript drafts for a three-year study he and Harmer E. Davis conducted for the International Road Federation. The study, published in 1977 and titled A Comparative Analysis of Urban Transportation Requirements, compares transportation needs in urban areas in fourteen countries, including the United States.
Another large portion of the papers found in Series 7. contains papers related to Turner's membership in various associations. Throughout his lifetime Turner remained devoted to groups such as the Highway Users Federation and the American Association of State Highway Officials. Correspondence, speeches, and conference notes related to these associations reflect his continued involvement in the transportation field almost until the year of his death.
The collection also includes correspondence, transcripts, and drafts of several reports recording the history of the interstate highway, a subject for which Turner was a popular informant. The most extensive project is a study by the Public Works Historical Society, commissioned by the American Public Works Association and the American Association of State Highway Transportation Officials.
