It's fascinating to see that while still a commercial hub, it pales in comparison to what it used to be. It was actually busy enough to warrant its own NYC crossing guard. Can you imagine that today?
There are some pictures I have of adjacent buildings that have been converted from storefronts to apartments. I imagine the death brought to Richmond Avenue (in Port Richmond) by the Plaza contributed to the death of such small shopping districts all over the North Shore in the late sixties and early seventies.
