Bridges are well thought-out as the crucial element in the current scenario of transportation infrastructure system as they regulate the volume of the traffic structure. If we don’t want to compromise the safety and integrity of our bridges, then it is extremely essential to strike a balance between traffic system and cost of construction. Bridge failure, is usually associated with serious loss to life and property. It is obvious that failure is the inability of one or more components of bridge to perform its functional requirement. This paper presents review of typical characteristics causes and mechanism of bridge failures. Main causes can be divided into natural disasters and unnatural disasters or human-made issues. Causes of bridge failures are strictly associated with topography type of structure, type of material, type of use, and age of bridge. Natural calamities including floods, scour, wind, earthquakes, landslides, debris in streams, and squall surges can occasionally become unavoidable and are the main reason why most bridges fall. Bridge collapses can also be caused by man-made factors, such as poor design and construction techniques, natural disasters, and some unnatural risks including vehicle overloading, fire, enemy or extremist attacks, poor inspection and maintenance, etc. Sufficient rigidity and flexibility are essential for all kinds of bridges in order to lower the likelihood of bridge failure caused by severe weather conditions.
