"Plan of the Center of the City, Showing the Present Street and Boulevard System"

This elegant and visionary map shows how the new thoroughfares would, if built, frame the redesigned central harbor and piers, Grant Park, and the grand civic center and plaza to be built to the west of the Loop. Just as dramatically, it shows how the construction of the diagonal avenues would entail the destruction of many existing blocks in the heart of the city. This, in fact, happened only in the case the extension of Ogden Avenue. This old Indian Trail and plank road historically terminated at Union Park (the trapezoidal green space in the upper right of the map). Its extension to the northeast (i.e., the lower right of the map) and a new terminus at Lincoln Park was achieved in stages during the 1920s and 1930s. This was done partially through construction of a viaduct over industrial land adjacent to the Chicago River. However, even this extension was short-lived. After the Second World War, leaders of the effort to redevelop the lakefront residential neighborhood known as Old Town targeted the Ogden Avenue extension as an eyesore and disruption of the historic fabric of the neighborhood. Almost all of the extension closed and redeveloped by 1992.
