Road infrastructure is a critical driver of socioeconomic development in Sub-Saharan Africa, facilitating connectivity, trade, and access to essential services. However, the construction and maintenance of roads have unintended ecological and epidemiological consequences, particularly in relation to malaria transmission. Roadworks often create artificial water bodies, borrow pits, and poorly drained depressions that provide ideal breeding habitats for Anopheles mosquitoes, the primary vectors of malaria. Simultaneously, improved human mobility along transport corridors accelerates the spread of Plasmodium parasites, linking high-transmission and previously low-risk areas. Empirical studies across multiple African countries demonstrate increased malaria prevalence in communities situated near major roads. Mitigation strategies, including eco-sensitive road design, effective drainage, routine maintenance, vector control interventions, and community engagement, are essential to reduce these risks. Future research should adopt interdisciplinary approaches integrating entomology, hydrology, public health, and infrastructure planning to guide sustainable road development that balances economic progress with malaria prevention.
