The Kabul–Kandahar Highway (NH0101) is 483-kilometer (300 mi) long that links Afghanistan's two largest cities, Kabul and Kandahar. It starts from Dashte Barchi in Kabul and passes through Maidan Shar, Saydabad, Ghazni, and Qalat until it reaches Aino Mina in Kandahar. It is currently being rehabilitated at different locations. This highway is a key portion of Afghanistan's national highway system or "National Highway 1". The entire highway between Kabul and Kandahar has no mountain passes but there are many mountains nearby in some places. Approximately 35 percent of Afghanistan's population lives within 50 km (31 mi) of the Kabul to Kandahar portion of the Ring Road.
