Sidu River Bridge, China
Becoming the highest bridge on Earth when it opened in 2009, the Sidu River Bridge is enormous. Spanning a deep, deep valley — the river below is more than 1,000 feet down — this is a structure that must be seen to be believed.
It’s more than 5,000 feet from end to end, a distance so great that the engineers tasked with building it had no option other than to use rockets to string the pilot lines from one side to the other. Close to Yesanguan in China’s Hubei province, the bridge forms an important route between East and West, linking Shanghai and Chongqing, and being much used as a result.
It isn’t for everyone though and, such is its height and the less-than-convincing cables that are strung from the giant H-shaped towers, some still prefer to take an alternative route through these mountainous lands. Not got a head for heights? This might be one to avoid.
