Via Boomershooter “Squirrel Hunter” we have the Karakoram Highway
The Karakoram Highway (KKH) is one of the highest paved international roads in the world. It connects the Xinjiang Uyghur Autonomous Region of China and Gilgit–Baltistan of Pakistan across the Karakoram mountain range, through the Khunjerab Pass, located at 36°51′00″N 75°25′40″E, at an elevation of 4,693 metres (15,397 ft).
Connecting China’s Xinjiang region with Gilgit–Baltistan region of Pakistan, the road is a popular tourist attraction. Due to its high elevation and the difficult conditions in which it was constructed, it is referred to as the Eighth Wonder of the World.
Wow! And I thought Idaho, Washington, Montana, and Colorado had some “interesting” switchbacks and high altitude construction on some of their mountain roads.
Nope. Nothing I have seen in the states even begins to compare.
