Spatial Inequality in Urban Road Infrastructure Provision: Evidence from Nasarawa State, Nigeria

Urban road infrastructure is fundamental to spatial integration, mobility, and socio-economic development. However, in many developing regions, the provision of urban roads infrastructure is spatially uneven, thereby reinforcing disparities in accessibility and development opportunities. This study assesses the nature of spatial inequality in urban road infrastructure provision across selected urban areas of Nasarawa State, Nigeria, namely Lafia, Keffi, Akwanga, and Nasarawa towns. The study adopts a mixed-methods approach integrating Geographic Information Systems (GIS), spatial network analysis, household surveys, field observations, and institutional assessments. Quantitative techniques such as connectivity indices, road density analysis, detour indices, and regression analysis were employed alongside qualitative thematic analysis. Findings reveal substantial disparities in urban roads infrastructure distribution and quality across the sampled urban areas. Lafia and Keffi exhibit relatively higher levels of connectivity and road network efficiency, while Akwanga and Nasarawa towns are characterised by fragmented and poorly integrated networks. The study further identifies institutional fragmentation, weak planning coordination, poor maintenance culture, and political influence as key drivers of spatial inequality in infrastructure provision. The absence of a gazetted urban hierarchy and integrated urban development framework significantly undermines equitable urban road infrastructure distribution within the state. The study concludes that spatial inequality in road infrastructure provision constrains accessibility, mobility, and balanced urban development in Nasarawa State. It recommends the formulation of an integrated urban roads development framework, strengthening institutional coordination, adoption of GIS-based planning systems, and prioritisation of equitable infrastructure investment strategies.
