NYC’s circulatory system and skin

If you’re teaching infrastructure and you need some metaphors to communicate how certain kinds of infrastructure operate, consider this: Street as vein and skin. 

“Streets are both New York City’s circulatory system and its skin.”

Part of New York 101 from the New York Times, Why are the streets always under construction?” is a great short, readable resource for students about the “subterranean layer cake” underneath the streets of any major city.
