The Old Seven bridge may crumble without support.
When the Old Seven Mile Bridge was built, it was an engineering wonder of the early 1900s. Part of Henry Flagler’s famous railway to Key West, it ran across nearly seven miles of open water to connect Marathon to the Lower Keys.
Today, the bridge is still a popular spot with both locals and tourists, but it’s slowly falling apart. Salt water and storms are eroding the bridge faster than the state can afford to repair it. Much of it is now closed. Historians and activists are desperately searching for a way to preserve what's left: a 2.2 mile section of the Old Seven Bridge that is still open to pedestrians and cyclists.
