Seven Mile Bridge, Florida

Besides being seven miles long, the bridge itself doesn’t seem that scary. But its position in the Florida Keys makes it a prime target for the region’s many hurricanes. In fact, the current bridge is the second iteration. The newer bridge scrapped the swing span concept of the original in lieu of a sturdier 65-foot-high arch to allow boats to pass by. While it may be sturdier, we still wouldn’t want to be on it during a storm.

Where: The Florida Keys, connecting the Middle and Lower Keys
.
Stats: 7 miles long; 65 feet high
