Seven Mile Bridge, Florida
The name says it all. Seven Mile Bridge is long — really long. Located in the Florida Keys, this feat of engineering links Knight’s Key with Little Duck Key and forms a vast network of bridges that span the beautiful waters here. Scenic it might be, but committing to a crossing can be a daunting experience. Once you’re on, you just have to keep going.
There are two bridges here — the original, which dates back to 1912, is now restricted to cyclists and pedestrians, although a large gap in the structure means that a full crossing is no longer possible.
The newer bridge teems with vacation traffic and, although this is much safer, certain risks endure. The sea bed is soft here and, for all its modern engineering, the bridge still sits on the foundations of a much older predecessor. Need to get across? Take a deep breath — and take your time.
