This study investigates the impact of infrastructure investment on port efficiency, focusing on Queen Elizabeth II Quay, in Sierra Leone. Using a mixed-methods approach, including Data Envelopment Analysis (DEA), regression analysis, and stakeholder surveys, the study evaluates the effects of infrastructure upgrades on operational efficiency, cargo throughput, and economic growth. Key findings highlight significant improvements, such as a 25% reduction in vessel turnaround times and a 30% increase in annual container throughput, attributed to investments in modern cargo handling equipment, berth expansions, and ICT systems. The study also highlights challenges, like maintenance limitations, insufficient finance, and regulatory inefficiencies, which jeopardize the long-term viability of these enhancements. Environmental factors, such as emissions from enhanced equipment, highlight the necessity of using sustainable technologies. Recommendations highlight the need to fortify public-private partnerships, improve governance structures, and include sustainable practices in forthcoming growth strategies. This study offers practical recommendations for politicians and port authorities, promoting a comprehensive strategy for infrastructure investment that harmonizes operational efficiency, stakeholder contentment, and environmental sustainability.
