The Seven Mile Bridge and Pigeon Key in The Florida Keys
The Seven Mile Bridge and Pigeon Key are seen from the air looking south from Marathon, Florida February 22, 2011. The Seven Mile Bridge connects Knight’s Key (part of the city of Marathon, Florida) in the Middle Keys to Little Duck Key in the Lower Keys. Among the longest bridges in existence when it was built, it is one of the many bridges on US 1 in the Keys, where the road is called the Overseas Highway.
