New Seven Mile Bridge

The New Seven Mile Bridge is the engineering backbone of the Overseas Highway, carrying traffic across open water between Marathon and the Lower Keys in one of the most dramatically scenic drives in the United States. Completed in the 1980s to replace the historic original, the bridge runs parallel to its predecessor and offers sweeping views of the Atlantic and Florida Bay from both sides as you cross. Driving the Seven Mile Bridge is one of those quintessential Florida Keys moments — water as far as the eye can see in every direction, with nothing but sky above and the long straight road ahead. It's the kind of crossing that makes the drive down the Keys feel genuinely extraordinary.
