worked on Wall Street vs worked in Wall Street?

I was wondering whether it is worked on Wall Street or worked in Wall Street. I guess it is "on", I am not sure why.

Solution 1:

Wall Street, in the context of this question, is a metonymn, like Hollywood, Broadway, The West End. We are referring to the financial sector based in lower Manhattan. "Worked in" is more appropriate when referring to metonyms, because you work in that particular industry but, unusually in the case of Wall Street, and Broadway "worked on" is a better fit. Maybe because they are streets. But then so is Whitehall, and politicians work in Whitehall, not on it.
