(part of which is "roofed", but which I guess has probably too much to do with transport to be right)

Park Place is the correct answer! I had lots of trouble with what seemed like simple questions on this one; sorry. I wasn't sure where to think of the boundaries (is it just the street, or does it include buildings?). And I didn't mean to mislead on the transportation question, but looking back I can see that perhaps I did suggest less of a connection than I should have. I think I was too focused on how small a street it is, and the fact that it doesn't really go anywhere...

Well, seems appropriate as I did slightly monopolise the questions at the end, there.
The next is ABSTRACT (Yes, sorry, another abstract but everyone will definitely have heard of it and many will have first-hand knowledge)

Hmm. I did have a Rosie-like moment at that answer. It's only after the fact that I've discovered the Atlantic City - Monopoly link (that makes the question worthwhile from my pov). On my own I'd probably have needed another half-dozen questions to get there.
