The Cape to Cairo Road or Pan-African Highway, sometimes called the Great North Road in sub-Saharan Africa, was a proposed road that would stretch the length of Africa, from Cape Town to Cairo, through the Cape to Cairo Red Lineof British colonies. The proposal was similar to the Cape to Cairo Railway, another proposed infrastructure project through the same colonies. Neither were completed before British colonial rule ended in the colonies.
In the 1980s the plan was revived with modifications as the Cairo–Cape Town Highway, known as Trans-African Highway 4, in the transcontinental roadnetwork being developed by the United Nations Economic Commission for Africa (UNECA), the African Development Bank (ADB), and the African Union, as part of the Trans-African Highway network. If finished it will be the third longest highway in the world after Highway 1 in Ausrtralia and the Pan American highway in the Americas
