A01 highway

Highway 1 or A01, formally called the Ring Road (Pashto: د افغانستان حلقوي سړک‎; Dari: شاهراه حلقوی افغانستان ‎‎), is a 2,200 kilometre two-lane road network circulating inside Afghanistan, connecting the following major cities (clockwise): Kabul, Maidan Shar, Ghazni, Kandahar, Delaram, Herat, Sheberghan, Mazari Sharif, and Puli Khumri. It has extensions that also connect Jalalabad, Bamyan, Khost, Lashkargah, Zaranj (Route 66), Islam Qala, and Kunduz. It is part of AH1, the longest route of the Asian Highway Network.

Part of Highway 1 has been refurbished since late 2003, particularly the Kabul–Kandahar Highway, with funds provided by the United States, Saudi Arabia and others. Most work on that stretch was done by Turkish, Indian and local companies. Japanese companies were also involved near the southern Afghan province of Kandahar. In the west, Iran participated in the two-lane road construction between Islam Qala and the western Afghan city of Herat. Pakistan rebuilt the Jalalabad–Kabul Road.
