Karakoram Highway (1959-1978)
China and Pakistan spent nearly two decades carving a 1,300-kilometer highway through the Karakoram and Himalaya ranges, connecting Kashgar to Islamabad. The route required blasting through some of the world's toughest mountain terrain and claimed hundreds of workers' lives.
Opened in 1978, it became the main overland trade and strategic link between China and Pakistan.
It set the template for China's high-altitude infrastructure ambitions across Central Asia.
Kashgar is the same starting point as the CKU railway — the new project extends China's mountain infrastructure push westward, swapping road for rail.
