To lay the first cable for a bridge in China, they used a rocket!
The Sidu River Bridge is the tallest bridge in the world as it is suspended over a 500-meter (1,600 feet) deep valley of the Sidu River. The bridge is 1,222 meters long, and cost approximately $100 Million to construct.
The interesting thing about constructing the highest bridge in the world, is that you have to get a little creative when laying down the cables.
Since there wasn't any machinery tall enough to bring the suspension cable from one side to the other, engineers had to use a rocket to lay the first cable!
