Seven Mile Bridge

Stretching across the turquoise waters of the Florida Keys, the Seven Mile Bridge is one of the most iconic landmarks in the state. Located at the southern end of the Florida Keys, this remarkable bridge connects Knight’s Key in Marathon to Little Duck Key, offering a scenic drive that has become a highlight for travelers exploring the Overseas Highway (U.S. Route 1). Known as both a modern engineering marvel and a testament to the beauty of the Keys, the Seven Mile Bridge is a must-see destination for visitors to the area.
