Footpaths to Freeways: The Evolution of Michigan Road Maps is an exhibition now on display (until June) on the fourth floor of the west wing of Michigan State University’s Main Library; if you can’t visit, there is this online version. It starts surprisingly early, in 1809, with one of the first maps depicting roads in the Michigan Territory. Were you thinking that “road maps” meant something later? I certainly was. Anyway, clicking on the maps opens up the usual Zoomify interface, but you’re getting samples rather than an archive: this is an exhibition, not a collection. Via MapHist.
