M41 highway

The M41, known informally and more commonly as the Pamir Highway (Russian: "Pamirsky Trakt", Памирский тракт) is a road traversing the Pamir Mountains through Afghanistan, Uzbekistan, Tajikistan, and Kyrgyzstan in Central Asia. It is the only continuous route through the difficult terrain of the mountains and serves as the main supply route to Tajikistan's Gorno-Badakhshan Autonomous Region. The route has been in use for millennia, as there are a limited number of viable routes through the high Pamir Mountains. The road formed one link of the ancient Silk Road trade route.

Route description

Sources disagree on the termini of the highway, with Mazari Sharif, Afghanistan; Termiz, Uzbekistan; Dushanbe, Tajikistan; and Khorog, Tajikistan all being offered as the beginning of the highway. All sources, however, agree that the highway ends in Osh, Kyrgyzstan. Today, the route is part of the M41 highway, which starts at Termiz at 37°12′39″N 67°16′20″E / 37.21083°N 67.27222°E / 37.21083; 67.27222 and ends at Kara-Balta to the west of Bishkek, Kyrgyzstan at 42°49′40″N 73°52′53″E / 42.82778°N 73.88139°E / 42.82778; 73.88139. The route passes northward through Termiz before turning east and crossing into Tajikistan. It then follows a general eastward route through Dushanbe, the capital of Tajikistan, to Khorog, crossing the Kafirnigan, Vakhsh, and Bartang Rivers. From there, it continues east for about 310 kilometers to Murghab, where it crosses the Murghab River. The highway then passes through the 4,655-meter (15,270 ft) high Ak-Baital Pass and past Lake Karakul before crossing into Kyrgyzstan to its terminus in Osh. The stretch of road between Khorog and Osh attracts a small amount of tourism due to its rugged natural beauty.
