Seven Mile Bridge

Iconic causeway spanning seven miles of open water, paralleled by the ruined piers of the original rail bridge.

Seven Mile Bridge is a fixture of the Leonida Keys, the island chain that stretches south from the mainland into the reef. Iconic causeway spanning seven miles of open water, paralleled by the ruined piers of the original rail bridge. Expect slow two-lane traffic, pastel-painted conch houses, and the steady background sound of outboard motors and wind.
