Roads are essential to facilitate interactions in cities. A sub-optimal road layout in cities and towns may inhibit interactions and constrain urban population growth. Using data from over 1800 cities and towns from Sub-Saharan Africa, and an instrument based on the history of foundation ages of cities in Africa, we study the relationship between the road layout of a city and its population growth. We show that cities characterised by low road density in the city centre experience less population growth in recent decades.
