Which highway in Central Asia is one of the highest, traversing the Pamir Mountains?

The high Central Asian highway that traverses the Pamir Mountains is the Pamir Highway.

The name most commonly refers to the M41 route, which crosses Afghanistan, Uzbekistan, Tajikistan and Kyrgyzstan. It is more than 1,200 kilometres long and serves as a vital link through some of the world’s most remote mountain terrain, especially Tajikistan’s Gorno-Badakhshan region.

Much of the modern road was built during the Soviet period, particularly in the 1930s, though the corridor follows routes used for centuries, including links associated with the Silk Road. Its most famous high point is the Ak-Baital Pass in Tajikistan, at about 4,655 metres.

The Karakoram Highway is a frequent mix-up because it is also a dramatic high-altitude international road, but it runs between Pakistan and China. The Friendship Highway instead connects Tibet with Nepal.
