Miami has the Golden Glades. The intersection of I-95, Palmetto Expressway, US441 (surface) and SR9 (surface), It's not that impressive looking but it is hell to navigate. It's the only interchange I've seen where you have to exit onto surface roads, including a stop light, to get from one highway to another.'
But it also has a great view of Miami's skylines from atope the HOV lane which flys over the whole thing.
