The Karakoram Highway is a 1,300 km (810 mi) national highway which extends from Hasan Abdal in the Punjab province of Pakistan to the Khunjerab Pass in Gilgit-Baltistan, where it crosses into China and becomes China National Highway 314. The highway connects the Pakistani provinces of Punjab and Khyber Pakhtunkhwa plus Gilgit-Baltistan with China's Xinjiang Uyghur Autonomous Region. The highway is a popular tourist attraction and is one of the highest paved roads in the world, passing through the Karakoram mountain range, at 36°51′00″N 75°25′40″E at maximum elevation of 4,714 m (15,466 ft) near Khunjerab Pass. Due to its high elevation and the difficult conditions under which it was constructed, it is often referred to as the Eighth Wonder of the World. The highway is also a part of the Asian Highway AH4.
