Road infrastructure has been identified as a major factor for sustaining urban mobility and requires constant investment in the form of budgetary allocation for construction, rehabilitation, and maintenance. To this end, the study assesses government investment in road infrastructure in Kogi State, Nigeria and how it impacts urban mobility. The study adopted a mixed-method research design and deployed a questionnaire survey to elicit information from randomly selected 1,215 household heads. Also, data on the state’s budgetary allocation and road infrastructure expenditure from 2008–2018 were sourced. Findings shown that the year 2015 received the highest budgetary allocation for road infrastructure and there is a statistically significant trend difference in the development of road infrastructure in the area. The results revealed that the annual road infrastructure expenditure has a statistical influence on the state’s general sectoral budget (F𝟏𝟏𝟗𝟗 92.776, p=0.000<0.05). Meanwhile, residents’ perception analysis revealed that government investment on road infrastructure is fairly impactful in Adavi, Okene, Dekina, Ajaokuta, and Lokoja, somewhat impactful in Ankpa and Kabba-Bunu, and no impact was felt in Mopa-Amuro and Bassa-Oguma communities. The study recommends giving more priority and increasing budgetary allocations for road infrastructure towards improving urban mobility and logistics functions in the state.
