THE IMPACT OF ROAD INFRASTRUCTURE ON ECONOMIC DEVELOPMENT: A STUDY OF FEDERAL ROADS IN LAGOS STATE.
Abstract
This study investigates the impact of federal road infrastructure on economic development in Lagos State, Nigeria, focusing on key economic indicators such as productivity, employment, trade, and market access. Utilizing a mixed-methods approach, the research combines primary data from 400 questionnaires and 20 semi-structured interviews with secondary data from sources like the National Bureau of Statistics (NBS), Federal Roads Maintenance Agency (FERMA), and recent journal publications (2020-2025). The study employs stratified random sampling to ensure representation across Lagos’ diverse population, targeting commuters, business owners, transport operators, and government officials in areas like Lagos Island, Mainland, Ikeja, Badagry, and Epe. Descriptive statistics, correlation, and regression analyses were used to test two hypotheses, confirming significant positive relationships between road quality and economic productivity (r = 0.62, p < 0.001, R² = 0.38) and between road investments and employment rates (β = 0.42, p < 0.001, R² = 0.32). Findings reveal that while federal roads, such as the Lagos-Ibadan Expressway and Apapa-Oshodi Expressway, enhance trade and contribute to Lagos’ 35% share of Nigeria’s GDP, challenges like poor maintenance (60% dissatisfaction), flooding (75% agreement on disruptions), and congestion (costing $1 billion annually) hinder optimal economic benefits. Qualitative insights highlight maintenance deficits, corruption, and the need for climate-resilient designs. The study aligns with Endogenous Growth Theory, emphasizing infrastructure’s role in long-term productivity. Recommendations include strengthening maintenance systems, investing in resilient infrastructure, expanding public-private partnerships (PPPs), integrating multi-modal transport, and improving governance to maximize economic impacts. These findings contribute to academic discourse on infrastructure-economy linkages and provide actionable insights for policymakers to enhance Lagos’ role as Africa’s economic hub.
