You probably ride a bridge every day while driving, but it is unlikely to put your stomach at the test and cause vomiting.
From those who sway to those who are surely too small to be stable, here are the 20 most scary bridges in the world.
Royal Gorge Bridge, Colorado
This extreme bridge is not only the tallest suspension bridge in the United States, but it also has an interesting history. It was built in 1929, but was not equipped with stabilization cables until 50 years later, it must have been a scary ride! Since then, it has become a tourist attraction and it even has a gondola for the bravest.
