Not that I've gazed at alleyways in very many cities in the US, but I was astonished to see that Boston, MA names its alleys (e.g. see image below). That was a first for me.
So.. I wanted to ask if it's a common occurrence in US cities and if Metropolis might have (or if we have seen in the series) named alleys?
Thanks,
