Inadequate roads are a major impediment to trade, development and poverty reduction in Africa. What would it cost to fix this long-standing problem? How large would the benefits be? Who should do it? World Bank researchers used spatial analysis and econometric techniques to quantify the costs and trade-expansion potential of a network of primary roads connecting all Sub-Saharan capitals and other cities with more than half a million people. They show very large potential payoffs for a continental network upgrading program. More tentatively, they suggest institutional and administrative arrangements for coordinated development and long-term donor financing of the proposed trans-African road network.
