…and I have no clue how they do it with any kind of accuracy!

The Chinese are constructing the world’s largest highest bridge called the Siduhe Grand Bridge. This bridge is over 2,100 ft. tall, which makes it higher than any skyscraper in the United States by about 360 ft. This bridge is not only tall, but it is also about 3/4 of a mile long, making the combination of construction over a valley with that long of a span creating some really interesting contructability issues.

Well, China has their solution…use rockets to launch the suspension cables across the valley to construct the main supports. Instead of normal methods such as helicopters, they actually launched the cable across. The weight of those cables alone had to make the rockets fly awkwardly, but they have successfully launched them.

Check out the pictures below to see their method!
