This work tries to assess the impact of government investment in engineering construction, communication technology and transportation on economic growth in Nigeria. One null hypothesis guided the study and data was collected from 1977 to 2008 from Central Bank of Nigeria statistical bulletin. Data were analysed using regression, F and t tests, stationary and co-integration tests. Results revealed that increases in government expenditure in engineering construction impacted more significantly on economic growth than their expenditure on transport and communication. Increased expenditure on all sectors was recommended especially on engineering construction. In addition policy modifications are needed to ensure that government expenditure on the transportation and communication sector achieve greater impacts on economic growth.
