The study investigated the nature and direction of causality among road transport infrastructure development, economic growth and poverty level in Nigeria. These were with the view to providing information on the extent to which road infrastructure development influence economic growth and poverty reduction in Nigeria. The study used secondary source of data collection of annual time series data from 1980 to 2012 and VECM techniques was adopted. The findings showed that, road transport infrastructure development and economic growth were the sources of poverty reduction in the long run (F = 5.7, p>0.05) and that poverty reduction and economic growth could influence one another in the short run (F= 3.0, p>10). Therefore, the study concluded that road transport infrastructure development and economic growth could be seen as useful policy as it has the potential to contribute to the pace of poverty alleviation and vice-versa in the Nigerian economy.
