A very, very cool map of major Roman roads done in subway map style:
Made by Sasha Trubetskoy, statistics major and designer, artist, and geography and data nerd.
Really fascinating! I know there were also some Roman roadworks running at least partially across the land from east to west along Hadrian’s Wall in Britain, but I don’t know whether there ever was a complete major road there.
Note: I wasn’t paid or perked to mention this; just passing along a good thing.
