It’s the original railroad bridge built by Henry Flagler
Few places capture Florida history, natural beauty and recreational bounty like the Old Seven Mile Bridge in the Florida Keys.
If you arrived in Florida before 1982, this was THE Seven Mile Bridge and driving the narrow two lane bridge was a white-knuckle experience. Today, there’s a sleek new bridge and the only portion of the historic bridge that was preserved for people to access was a 2.2 mile section that had been popular with fishermen, folks watching the sunset and bicyclists.
After years of deterioration, this small section of Old Seven, as it is nicknamed, is being restored and is scheduled to reopen in 2021.
Saving Old Seven had been a major cause in the Keys and in 2014, three levels of government came together to fund a major restoration project. Under the plan, the county, the City of Marathon and the Florida Department of Transportation all contribute. FDOT pays $57 million over a 30-year period; Monroe County pays $14 million and the City of Marathon pays $5 million. When the bridge is refurbished, it will be able to hold 17-ton vehicles, such as fire trucks.
The first phase of the project began in 2017. That $2 million project created a handicapped-accessible walkway from the old bridge under the new bridge to the ocean side. It will include adding picnic pavilions and scenic overlooks. In 2019, a $1.9 million portion of the project was underway — building an exact replica of the wooden “off ramp” that leads to Pigeon Key. Details are here. Along the entire 2.2 mile stretch, crews are replacing some of the rusted steel beams and strengthening the concrete piers that support the bridge.
History of Old Seven Mile Bridge
The history of the Old Seven Mile Bridge is closely tied with Florida’s history — Henry Flagler’s railroad down the east coast of Florida is what opened the state to the world. For better or worse, Florida is what it is because of Henry Flagler.
His overseas railroad, the first land route ever from Miami to Key West, never was a financial success and then it became a downright disaster. A devastating 1935 hurricane brought 200 mph winds and a 17-foot storm surge, washing away miles of railroad. Flagler’s bankrupt Florida East Coast railway sold the whole right-of-way to the state for one-seventh what it cost Flagler to build the railroad.
The Seven Mile Bridge was easily converted by the state of Florida to an automotive bridge — that’s the surface you bike or walk today. Until 1982, when the adjoining new bridge opened, it was the only road cars could take to Key West.
Folks in the Keys treasure the Old Seven Mile Bridge and, before it closed for repairs, used it daily. In season, it would fill up each night with people savoring the famous Florida Keys sunset.
The other 5.8 mile section of the Old Seven Mile Bridge south of Pigeon Key cannot be accessed– a section was removed south of the island to prevent that — and today the remaining expanse rusts in the sun and solitude, with an occasional tree finding enough dirt in a crack to sprout from it.
When you visit the Old Seven Mile Bridge, it may look familiar. It has appeared in several films, most famously the 1994 True Lies with Arnold Schwarzenegger, when the old bridge is shown being destroyed by missile strikes. (The explosion was done on an 80-foot model.)
Visiting Pigeon Key: Where the Old Seven Mile Bridge started
Few history lessons are as beautiful as this one: A visit to Pigeon Key, a picturesque little island surrounded by dazzling blue water in the middle of the Old Seven Mile Bridge.
There are lots of places I love in the Florida Keys, but Pigeon Key is at the top of the list.
Here’s what I love: spectacular views, its isolation from the outside world, an amazing human story, charming historic buildings, snorkeling off the dock and the fact that the island gets 95% of its energy from solar power.

Many readers have written to ask: Can you bicycle across the Seven Mile Bridge?
You could only do this on the new bridge, I wouldn’t do it — but, then, I’m a recreational bicyclist who is looking for stress-free, safe trails. It is not recommended for that kind of ride!
Many bicyclists do it. There’s about a five-foot lane for bikes and the bridge is mostly flat, with about one-mile at the center elevated, according to a bicyclist who has written about it. Here’s a section of her account on pedaling the length of the Keys.
