I found this 1925 traffic count map on the Library of Congress website while looking for maps by Howard Fogel, last week’s mystery cartographer.
This blueprint style map uses line thickness. I like how they hollowed out the big cities, otherwise the thick lines would take over the entire area. It also lists traffic counts, which at the time could range from 8,000 daily vehicles traveling north from Chicago,
to a mere 50 or so south of Buffalo in western South Dakota and 65 between Buffalo and Bison (what we call buffalo are really bison, not true buffalo if you like being picky).
There were 6,000 cars heading west from Milwaukee. Today’s Wisconsin DOT Traffic Counts Map shows 166,000 daily cars.
