Transportation infrastructure is associated with economic development, but it can also be used for social control and to benefit the governing elite. We explore the connection between the construction of road networks, state-led repression, and land allocations in the longest dictatorship in South America: Alfredo Stroessner military regime in Paraguay. Using novel panel data from the truth and reconciliation commission, we show that proximity to roads facilitated state-led repression and the illegal allocation of agricultural plots to dictatorship allies. These results suggest that infrastructure projects can also hinder economic development.
