Abstract: This study examines the impacts of transport infrastructure investments on Cameroon's economic growth and poverty reduction, using a dynamic computable general equilibrium model and microsimulation. Analysing road, rail, air, and water transport, results show road infrastructure has the largest impact, with positive contributions from other modes. However, benefits diminish without sustained investment. The paper advocates for a balanced strategy, prioritising continuous upgrades and expanded rural road networks to mitigate regional inequalities and promote inclusive growth. In Cameroon, where transport is vital for economic transformation, this research highlights the need for strategic, long-term infrastructure investment to ensure equitable and sustainable development.
