This is the Yaxi Expressway in southwest China's Sichuan province. It features some of the highest and longest bridges in the world.
Here's a little article about it: https://themindcircle.com/yaxi-expressway-traversing-the-clouds/
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.
Western countries do stuff like this, too. Engineering is amazing the world 'round.

Yeah, Millau is very impressive too. It's also very pretty to look at. The thing about China though is that it builds a lot of these things. Like just look at a list of the world's highest bridges and viaducts and you'll see China massively overrepresented, especially at toward the top: https://www.highestbridges.com/wiki/index.php?title=List_of_Highest_International_Bridges%2FPage_1
(This is a really cool page if you're a bridge nerd like me btw; fun fact i learned from it: China's Guizhou province alone has more high bridges in it than every other country on earth combined...)
So yeah, this sort of thing happens in the West also, but it's not super common, so when it does it feels really special. The Millau viaduct is fairly famous here in Europe. In China it feels like the country is full of this type of infrastructure, so to Chinese people it must feel almost banal.
