This is the Yaxi Expressway in southwest China’s Sichuan province. It features some of the highest and longest bridges in the world.

Side note: am i the only one who finds this crazy scary to look at? I’m sure it’s awesome driving on it, but looking at it from afar it looks wild.
No, I’m with you yeah that does look scary. I’m no engineer but it’s hard to believe these spindles are holding all that concrete.
The road is also wavy, and that probably is factored in. I’d imagine it imparts a significant lateral stability to it, like those wavy brick walls that are only a single layer of bricks thick; they seem like you could just push them over, but you definitely can’t.
