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.
i've had people drive in from neighboring [US] states and be absolutely terrified of our urban highway interchanges [texas][many of them also sky-high but not quite this high I don't think? - for reference, youtube practical engineering-why are texas highway interchanges so tall], imo it (the concern/fear?) is just something you might just be used or unused to
Yeah, those tall interchanges are freaky too. Impressive engineering is awesome to look at no matter where it is in the world.
In parts of New York there are similar ones that are crumbling/shut-down and falling on people.
