Overseas Highway (Florida Keys)

One hundred and thirteen miles from Miami to Key West, hopping across 42 bridges over open ocean. The Seven Mile Bridge is the showstopper — nothing but turquoise water on both sides and the feeling that your car is driving on the surface of the sea. Henry Flagler built the original railroad version in 1912; the Labor Day Hurricane of 1935 destroyed it. The highway replacement opened in 1938. End the drive at Mile 0 in Key West, grab a key lime pie, and toast the sunset at Mallory Square.
