Royal Gorge Bridge in Colorado, USA

If you’re acrophobic, don’t even think of using the Royal Gorge Bridge in Colorado. It’s one of the highest suspension bridges in the United States and the seventh-highest in the world. The 1000-foot-high structure fits between two massive mountains in Cañon City and runs above the famous Arkansas River.

The government inaugurated the Royal Gorge Bridge in 1929, having built it as a tourist attraction. And it has served that purpose for close to a century. Unlike other bridges that took years of construction, this 268-meter-long structure only took six months, thanks to its funders, the Royal Gorge President and the Amusement Company.
