A global history of the road. Road construction, maintenance and use in Colombia,
Argentina, French West Africa and the Algerian Sahara, 1930-1970
From 1930 to 1970, the roads of Latin America, Africa and Asia experienced considerable
length increase and, especially in the post-1945 period, the modification of their material
characteristics. This transformation enabled the road structures and surfaces to withstand
the rapidly increasing heavy traffic of a globalising and nationalising world. This thesis
shows the importance of unpaved roads and freight transport, particularly in the developing
world. It argues that many roads, especially in the developing world, were built as what were called low-cost roads. Built down to a price, rather than up to a standard, low-cost roads were designed to last half as long as high-quality roads. However, these roads were meant to be upgraded over time, therefore making maintenance and improvements essential to ensure future circulation. In fact, this thesis shows that maintenance and upgradeability were the crucial factors that allowed low-cost roads to bear the rapidly growing heavy traffic of the post-1945 period. This thesis therefore represents a shift away from the main themes of the existing historiography, which focus on private automobiles, motorways, tourism and leisure, and policy for road building. This thesis makes the case for studying the materiality of twentieth-century roads and focuses on the cases of the Algerian Sahara, French West Africa, Argentina and Colombia – allowing for a comparison of varied extreme natural environments and complex relationships between rail and road transport.

I am an historian of twentieth-century science, technology and the environment. After finishing my History undergraduate degree at the Universidad Nacional de Colombia, I completed an MA on Science, technology and medicine in history at King’s College London, where I am currently finishing my PhD thesis.
My research interests sit at the intersection of technology, transport and development policies, the natural environment and social inequalities at a global scale. I have experience conducting research addressed to academic audiences, policy-makers and the wider public.
