In 1956 President Dwight Eisenhower signed the historic Federal-Aid Highway Act that authorized construction of the National System of Interstate and Defense Highways, which came to be considered one of the United States’ greatest public works achievements. In Nebraska, the Department of Roads (NDOR) began planning for a state-wide system of freeways. Part of their planning included an expressway system for the Omaha area. The map shown below, from 1957, illustrates the “Recommended Expressway System” for Omaha. Several years later, NDOR modified this plan to include extending the North Expressway to connect with the expressway circling the northern side of the metro area.
