A dark bronze plaque with raised lettering is set into a pale concrete wall in the sun. It reads: A Modern Civil Engineering Wonder of the United States, One of Seven Selected by the American Society of Civil Engineers, 1955; a small blue shield, the emblem of the society, sits between the lines. In 1955 the society chose seven works of American engineering as the modern wonders of the country, among them Hoover Dam.
