Seven Mile Bridge

The Seven Mile Bridge is a bridge in the Florida Keys that connects Knight's Key to Little Duck Key and it is, of course, seven miles long. It is one of the longest bridges in existence when it was constructed and is part of the numerous bridges making up the route from Miami to Key West along US 1 known as the Overseas Highway. Travelers will note there are two bridges in the area. The first one, which was called the Knights Key-Pigeon Key-Moser Channel-Pacet Channel Bridge, was built by Henry Flagler in 1912. This was part of Flagler's Oversease Railroad. The bridge was damaged in the 1935 Labor Day Hurricane and turned into an auto bridge by the federal government. This was a drawbridge that allowed boat traffic to pass. This bridge was damaged in 1960s Hurrican Donna and gradually became undrivable, but it used as a fishing pier still today. The current Seven Mile Bridge was constructed between 1978 and 1982. This bridge is made up of 440 spans and provides a 65-foot clearance for boats. The length is actually just 6.79 miles long, which is shorter than the original. The bridge hosts a fun run in April that lasts about two and a half hours and because this is the only route down US 1 between the Keys, travelers must hold off on driving.
