This paper presents a review of bridge failure and its direct; indirect consequences statistics, based on a literature survey and available information through websites, focusing on RCC; PSC; steel composite bridges. Failure cases have distinguished between those resulting in bridge total collapsed and partially collapsed, but resulted in the loss of serviceability. Classification of the most common failure causes and modes of failure is undertaken. The bridge failure results indicate that collapses due to natural hazards, design errors and limited knowledge are the most commonly encountered in bridges, followed by accidents and human error. When analyzed chronologically, the data demonstrate a decreasing trend for the collapses attributed to limited knowledge and an increasing trend in failures resulting from accidents and natural hazards. The findings obtained through the study of the failure of these bridges prove to be great values as these studies provide a big database to civil Engineer to enhance their knowledge to identify the causes of their failure. By Studying and evaluating the failure of these bridges, similar mistake can be avoided in the future by learning from the past. The trends revealed through statistical analysis can aid in identifying the potential of the most significant hazards affecting bridge structures and help in planning against their consequences. In terms of non-collapse cases, fatigue failures are found to be predominant in steel bridges. The paper concludes with a discussion of bridge failure consequences and their significance in risk assessment of bridge structures.
