Pakistan's Karakoram Highway runs over the 15,400-foot Khunjerab Pass and links the middle eastern country to China. Also known as the international "Friendship Highway," the road travels along the route of the old Silk Road winding through gorges. While the road links two countries, it remains unpaved on the Pakistani side and unstable most of the time. Prone to landslides and flash flooding, Karakoram Highway claimed the lives of almost 900 workers during its construction.
