I have to say that aside from the Brooklyn, GW, and perhaps the Manhattan, many forget the numerous bridges in New York City (which is essentially the suspension bridge capitol of the US if not the World). Not to mention the numerous amount right outside the city in Jersey.
Many also typically get the Bronx-Whitestone, Throgs Neck, and Verrazano confused for all the same one.
I've also had people confuse the Bayonne Bridge for the Hellgate.
All in all I never take for granted the bridges of New York City.
New York, New York- A city so nice they named it twice.
