Is the Karakoram Highway the "Eighth Wonder of the World"?

No official "Eighth Wonder of the World" designation exists. The Karakoram Highway (KKH)—the 1,300 km paved road linking Hasan Abdal, Pakistan to Kashgar, China across the Karakoram Mountains—is sometimes called that in tourism marketing and travel writing, but it's a superlative, not a formal title.

The original Seven Wonders were ancient Mediterranean structures. Modern lists (New7Wonders, UNESCO sites, engineering marvels) vary widely. The KKH is a legitimate engineering feat: built 1966–1978 by Pakistani and Chinese workers at extreme altitude, through active landslide zones, across the Khunjerab Pass (4,693 m / 15,397 ft). It's the world's highest paved international road.

Call it spectacular. Call it an engineering wonder. Just don't cite it as an officially numbered wonder.
