Sidu River Bridge
The Sidu River Bridge is another dangerous bridge on the list and the highest in the world, as it suspends over a valley with a depth of 1,600 feet. The Sidu River Bridge is located in China and is around 4,000 feet long, making it one of the largest in the world.
China spent around $100 million to construct the bridge, which was completed in 2009. Driving over this bridge is quite scary as it is a very long way down to the bottom, but it does offer some great views of the surrounding landscape, just be sure to pay attention while driving.
