Misinterpretation in "Crossing Brooklyn Ferry"

I think that in reading Whitman's "Crossing Brooklyn Ferry" so many people instinctively associate it with the brooklyn bridge because it's the most commonly thought of mode for transportation between the two boroughs. There's no more ferry, only the historic figure of the bridge that practically everyone has seen or knows about in one way or another. I believe some people read Whitman's poem and automatically modernize it by inserting what they presently know to be just as mythical as the old brooklyn ferry in Whitman's world, all because of the lore surrounding the great bridge that everyone has come to cherish.
