The Kabul–Kandahar Highway is said to have been designed and
asphalted in the 1960s by Afghan and American engineers under contracts with the
United States International Cooperation Administration. This was a time when the
Soviet Union and the United States were spreading influence in Afghanistan. In those years the highway was used mostly by trucks and
couch buses because private vehicles were not as many as today. In the 1980s, military convoys of the Soviet Union were often seen passing back and forth between Kabul and Kandahar. The highway began deteriorating in the 1990s. In September 2002, during the government under
Hamid Karzai, the United States funded the repair and rebuilding of of road (at a cost of about $190 million), while
Japan funded . Only about of the highway was usable prior to the repairs. The contract to rebuild the highway was awarded to the
Louis Berger Group, a private American company based in
New Jersey, which completed the work with
Afghan-American,
Turkish, and
Indian subcontractors. Phase one of the paving was completed in December 2003. In 2022, due to the increase of
head-on collisions, the current government decided to turn it into a modern
divided highway. Work soon began in sections of the highway in different provinces of the country. Construction of a temporary
toll plaza began in Kabul Province in late 2022. Another toll plaza is planned to be constructed in Kandahar Province. In 2025, construction began on major bus terminals next to the highway. One is in the Arghandi area of Kabul province and the other in the
Daman district of Kandahar province. It will take three years to complete. Currently the
Dashte Barchi bus station provides transport services to the provinces of
Maidan Wardak,
Bamyan,
Ghazni,
Daikundi and
Ghor. Another such bus station is in
Ayno Maina in Kandahar. The bus terminals are regulated by the
Ministry of Transport and Civil Aviation. 266 Cameron road ceremony with personnel - USACE-p15141coll5-15620.jpeg|Prime minister
