A questionnaire survey with 60 respondents was employed for the data, using a Likert scale questionnaire. The study used descriptive research design and quantitative research approach and the primary sources of data were collected from the questionnaire done on staff and management members from Ethiopian road administration. After conducting inferential statics it is found that there is a strong positive correlation between the dependent and independent variables. The finding suggests that organizations can avoid or minimize cost overrun by prioritizing those factors highly correlated with the dependent variable. Recommendations include creating a comprehensive management plan, predicting future economy fluctuations such as exchange rate and inflation, and the concerned body should facilitate payment to contractors in order to overcome delay in progress payment and avoid the occurrences of cost overrun. Based on the results and recommendations likelihood of successful project implementing in the road project of Ethiopian Road Administrations can be increased and improved.
