Corridor 6 connects Europe and the Middle East with South Asia (Afghanistan, Kazakhstan, Pakistan, Tajikistan, Turkmenistan and Uzbekistan). It unfolds from North to South, linking the Russian Federation with Iranian and Pakistani ports.
- Corridor 6a includes both road and rail routes, and links the northwest coast of the Caspian Sea to the Gwadar port of Pakistan, crossing the Russian cities Krasnyi Yar (road) and Aksaraskaya (railway), the Kazakh cities Kurmangazy (road) and Ganyushking (Uzbekistan), the Uzbek cities Karapalkastan (road and rail), Bukhara, Termez, the Afghan cities Hairatan, Mazar-e-Sharif, Kandahar and the Pakistani cities Chaman, Surab, Gwadar.
- Corridor 6b also includes road and rail routes, passing through almost the same countries as the previous one: it starts from Russia, more precisely from Novomarkovka (road) / Kos Aral (rail), reaching Kazakhstan in Zhaisan (road and rail), Aral, Saryagash / Yallama (rail) and Zhibek Zholy (road), and then Uzbekistan in Keles (rail) and Gisht Kuprik (road), Termez / Airatom (rail and road), continuing towards Afghanistan – Hairatan (rail and road), Islam Qala, and then Iran (Dogharoun) and again Afghanistan (Kandahar) to end in Pakistan – Chaman, Basima and Gwadar.
- Corridor 6c has the same starting point as 6b and it includes the same Russian and Kazakh cities, and also some Uzbek cities: from Khavast (Uzbekistan) it reaches Tajikistan, through Istaravshan, Kurgonteppa and Panji Poyon; it then enters Afghanistan through Shirkan Bandar, Kabul, Torkham (road) and, finally, it arrives in Pakistan, where it passes through the following urban localities: Landi Kotal (road), Lahore, Muzaffargarh and ends in Karachi port.
- Corridor 6d connects Russia (Krasnyi Yar – road and Aksaraskaya – railway) to Pakistani port Gwadar via Kurmangazy (road) and Ganyushking (rail) in Kazakhstan, Bereket, Ashgabat and Mary in Turkmenistan, Herat (Afghanistan) Kandahar (Afghanistan), Chaman, Surab and Gwadar (Pakistan).
- Corridor 6e is a railway extension linking Kazakhstan to Iran via Turkmenistan.

Corridor 6 includes 10,600 km of roads, 7,200 km of railways and 5 logistics centers, being a north-south connecting corridor with strategic importance as it connects landlocked areas with port areas.
There are thirty-eight projects developed along this corridor: six in Afghanistan, three in Kazakhstan, fourteen in Pakistan, six in Tajikistan, one in Turkmenistan, and eight in Uzbekistan. The projects aim at building roads along with the reconstruction of a railroad and a tunnel in Afghanistan, as well as rehabilitation and road and highway construction in Kazakhstan. Pakistan benefits from construction and overtaking of highways and railway rehabilitation, while in Tajikistan projects imply the creation of a logistic center and modernization of roads. The project in Turkmenistan aims at building the Atamurat-Ymamnazar-Aqina railway line. In Uzbekistan, projects concern rail electrification, road reconstruction and the reconstruction of the Termez Airport Complex.
