Across the country, the numerous named auto trails began creating problems for motorists. Many auto trails had confusing alternate routes and were not always the most direct routes; also, multiple different auto trails often overlapped on the same roadway. During the annual meeting of the American Association of State Highway Officials (AASHO) in San Francisco, California, in 1924, Minnesota state maintenance engineer A.H. Hinkle lobbied the organization to reorganize the nation's transcontinental highway system, suggesting a nationwide numbering system of well-located and direct interstate highways be implemented. AASHO agreed to Hinkle's ideas, passing a resolution on November 20, 1924, to develop a better organized interstate highway system. AASHO then sent a recommendation to the Secretary of Agriculture Howard M. Gore to create a joint board between the Bureau of Public Roads and state highway officials from across the nation to develop a new organized system of numbered interstate highways. Gore acted on the recommendation in 1925, establishing the Joint Board on Interstate Highways.
