Broadway is a great example of something having very long-lasting effects. It’s much older than a postal road, being originally formed as a footpath used by the local native tribes to travel up and down Manhattan. It roughly followed a ridge line that is not very evident in lower Manhattan today but becomes much more obvious when you get up to northern Harlem, Washington Heights and Inwood.

I remember reading it was a deer trail from long before humans arrived. Dilophosaurus trail before that, probably.
