African maritime hubs handle over 90% of the continent's import and export volumes but frequently rank lowest globally in operational efficiency. This study investigates the impact of digital port infrastructure—specifically Port Community Systems(PCS),Automated Gate Systems (AGS), and AI-driven container tracking—on reducing vessel turnaround times and cargo dwell times. Utilizing a mixed-methods approach, secondary performance data from five major African ports (Durban, Mombasa, Lagos-Apapa, Tangier Med, and Tema) were analyzed alongside qualitative insights from 250 maritime stakeholders. The results indicate that comprehensive digitization reduces port delays by up to 42% and slashes administrative clearance times from days to hours. Tangier Med and Tema serve as benchmark models demonstrating that automated infrastructure directly correlates with higher throughput and integration into global supply chains. The study concludes that standardizing digital frameworks across regional corridors is vital to mitigating global shipping bottlenecks
