1. Seven Mile Bridge, Florida
There are actually two Seven Mile Bridges, an old and a new. The Old Seven Mile Bridge was constructed in 1900, but as it fell into disrepair, the new bridge was built parallel to the old one between 1978-1982.
The old bridge remains open to pedestrian traffic for a short stretch of its length, but to get over the entire seven miles of the new bridge, you’ll need to drive. Be careful – the long overwater stretch can play tricks with your eyes.
