Keep your eyes on the road!

Interested in a truly stomach-flopping adventure? Take a journey over some of these bridges … the world’s highest. Warning: If you’re leery of heights, don’t look down. China boasts the lion’s share of the highest bridges, with 3 of the planet’s top 5. Tallest in the U.S. is the Royal Gorge Bride in Cañon City, Colorado (pictured here). At nearly 1,000 feet high, the bridge is taller than it is long. What’s the tallest bridge you’ve even been on? Did you look down?
