The problem of bridge bump has been a major issue for decades. Over the years, a lot of studies have been conducted by various agencies and professionals to investigate and pinpoint the cause of this phenomenon. Majority of researchers agreed that the major cause of the formation of bridge bump is the differential settlement of soil between bridge abutment and bridge approach. However the exact cause of the settlement may vary depending on the site condition. Some of the causes of settlement were discussed in this paper which includes deformation of embankment fill, deformation of foundation soil, poor drainage system in and around the bridge abutment and poor design and construction practices. Besides that, current practices and new development of mitigation and rehabilitation methods were also discussed in this paper. This paper reviews the factors that contribute to the formation of bridge bump while also identifying the available methods that was used to eradicate this problem.
