This paper is part of a major policy study by the World Bank. It contains rough estimates of the aggregate cost of rehabilitating and maintaining the main road networks of 85 developing countries. The estimates use information on the condition of the network in each country, norms on economically justified maintenance standards, and uniform unit costs of rehabilitation and maintenance works by geographic region. Totals are given by region of the rehabilitation backlog--more than $40 billion, not counting bridges and all minor roads--and future annual maintenance needed to prevent the backlog (totaling $4 to $5 billion per year) from growing. The 85 countries are classified according to the burden of rehabilitation and maintenance needs relative to gross national product (GNP) and the adjustment required from present levels of expenditure on roads, including new construction. The results show a varied picture: good in much of East Asia, bad in much of South Asia and Africa. Indeed many African countries will need to make a major effort over at least a decade, with both large increases in total roads funding and a radical shift from new construction to rehabilitation and maintenance, to prevent their networks from deteriorating further, let alone restore them to an economically warranted condition. Options for finding the funds needed are reviewed.
