The Mississippi River system, rendered as an urban transit network. This was the first one I created, as a proof of concept. It amused me enough to go on to make many more. Note that if you’d like a more detailed view of this massive river system, I’ve created several other maps which cover individual sections in detail. Check out my main river maps page to see them all.
