- The world's scariest bridges are known for their steep slopes and stomach-churning heights.
- Some bridges that may look terrifying are actually relatively safe to cross, like the Sidu River Bridge in China.
- Others, like the U Bein Bridge in Myanmar, may be on the verge of collapse.
On the morning of August 14, a fierce thunderstorm struck the Morandi Bridge in Genoa, Italy, sending the decades-old structure tumbling to the ground.
In the years leading up to the collapse, engineers had warned that the bridge might not be structurally sound, but the timing was ill-fated. Just as the bridge's maintenance company began to embark on repairs, the storm derailed their efforts.

Determining whether a bridge is "safe" is a complicated question. In the United States, one of out every ten bridges is considered "structurally deficient," meaning it's in need of significant maintenance or repair. That includes the Brooklyn Bridge, which carries more than 100,000 vehicles each day.
While it's difficult to tell if a bridge is dangerous just by looking at it, a few bridges are downright terrifying to cross no matter their stability.
We've rounded up some of the scariest bridges in the world, which are notable for their stomach-churning heights, rickety guardrails, and steep slopes that seem to defy engineering logic. Take a look.
