This simple map of main roads and expressways served as a minimalist route map for the Detroit Edison Co., what would become DTE Energy. The most interesting element is the typed title of the source and publisher of the map “Generation Engineering, Cartography.” DTE had a cartography division into the 1980s and I wonder how much of a bridge that team was from the grandiose maps and plans of Doxiadis commissioned by DTE to the present day mapping of power outages.

This map is part of the Hill Map Collection digitized in partnership with the Reuther Library and Archives as part of the Detroit Atlas Project funded in part by the WSU Union of Part Time Faculty (UPTF) Professional Development Fund.
