Introduction
Africa’s infrastructure development has long been a focal point for economists, policymakers, and international development organizations. Infrastructure is foundational for economic growth, social development, and the improvement of living standards. Inadequate infrastructure hinders countries from accessing markets, providing essential services, and fostering economic opportunities. This narrative explores the journey of infrastructure development in Africa, examining its historical context, current state, key projects, challenges, successes, and future prospects.
Historical Context
Colonial Era and Its Impact on Infrastructure
The colonial era significantly influenced Africa’s infrastructure landscape. Colonial powers primarily developed infrastructure to serve their economic interests, focusing on the extraction and export of raw materials. This period saw the construction of railways, ports, and roads that connected resource-rich areas to the coast but often neglected the development of intra-continental connectivity (Jedwab & Moradi, 2016). Consequently, many African countries inherited an infrastructure network that was ill-suited for independent economic development and regional integration.
Colonial infrastructure projects were largely extractive, aimed at facilitating the movement of raw materials from the interior to the ports for export. Railways, such as the Kenya-Uganda Railway, were built primarily to transport agricultural and mineral resources (Jedwab & Moradi, 2016). This focus on export-oriented infrastructure left a legacy of poorly connected regions within countries, limiting domestic trade and movement.
Post-Independence Efforts and Challenges
Following independence, African nations faced the daunting task of rebuilding and expanding their infrastructure. Initial efforts were hampered by limited financial resources, political instability, and a lack of technical expertise. During the 1980s and 1990s, structural adjustment programs imposed by international financial institutions often led to reduced public investment in infrastructure (Mkandawire, 2010). However, the turn of the 21st century marked a renewed focus on infrastructure development, driven by economic growth, increased political stability, and international support.
Countries began prioritizing infrastructure as a key driver of economic development. National development plans started to include significant allocations for infrastructure projects. For example, Ethiopia’s Growth and Transformation Plans (GTP I and II) have emphasized massive investments in infrastructure, particularly in transportation and energy sectors (African Development Bank, 2018).
Current State of Infrastructure
Transportation

The road network in Africa remains underdeveloped compared to other regions. While there have been significant improvements, many rural areas still lack all-weather roads, hindering access to markets, healthcare, and education. According to the African Development Bank (2018), about 53% of the roads in sub-Saharan Africa are unpaved, which poses significant challenges, especially during rainy seasons.
Key projects, such as the Trans-African Highway network, aim to improve regional connectivity and trade. This ambitious project envisions a network of nine highways, totaling 56,683 kilometers, intended to connect major cities across the continent (African Development Bank, 2018). Despite slow progress, segments of the highway network, like the Trans-Sahelian Highway, have shown the potential for enhancing regional trade and mobility.
Railways
Railways, once the backbone of colonial-era transport, have seen varying degrees of modernization. The Standard Gauge Railway (SGR) in Kenya, part of the larger Northern Corridor Integration Projects, is a notable example of recent investments aimed at boosting trade and reducing transport costs (World Bank, 2019). The SGR connects the port city of Mombasa to the capital, Nairobi, and plans are underway to extend it to neighboring countries.
Modernization of rail infrastructure is crucial for reducing the high transport costs that have long plagued African economies. For instance, the cost of transporting goods in East Africa is about 50% higher than in the United States (World Bank, 2019). By improving rail infrastructure, countries aim to lower these costs, enhance trade efficiency, and reduce the burden on road networks.
Ports
African ports are critical for international trade, yet many are operating beyond their capacity, leading to inefficiencies and delays. Significant investments are being made to expand and modernize ports like Mombasa in Kenya and Durban in South Africa, enhancing their competitiveness and capacity (OECD, 2017). The Port of Durban, for example, is undergoing extensive upgrades to handle larger vessels and increased cargo volumes.
Improving port infrastructure is essential for facilitating trade. Efficient ports reduce the time and cost of importing and exporting goods, making African products more competitive in global markets. Investments in port infrastructure are also complemented by improvements in logistics and customs procedures, further enhancing trade facilitation (OECD, 2017).
