It seems when speaking "Detroitese", interstate freeways are always called by their number[[94, 75, never the Ford, Fisher, or the Chrysler) and non-interstates are called by their name[[the Lodge, the Southfield, and the Davison never M-10, 39, or 8). In Chicago, all of the expressways are interstates but always referred by name[[the Dan Ryan, the Kennedy, never 94).
