Sidu River Bridge in China

China has a penchant for making mind-boggling structures, and the Sidu River Bridge is another one of the country’s masterpieces. This world-renowned structure is a suspension bridge that connects two disparate parts of the nation: the mainland and Hubei province. Before the government built the bridge, it wasn’t easy to travel through multiple rivers and mountainous terrain.

The magnificent engineering feat was part of the country’s ever-expanding highway system, but its placement is so high that it sends shivers down one’s spine. The idea of driving over it is scary enough, much less walking across. Kudos to the spirited workers who pulled building this off!
