The conventional bridges use expansion joints and bearings to accommodate the thermal movements of the bridge. However, they don't completely eliminate the distress caused because of the expansion and contraction of deck. In turn, they create maintenance and installation problems associated with the joints. In this regard, Integral Abutment Bridge (IAB) is an effective and economical alternative for conventional bridges. The IABs eliminate the need to provide deck joints and thereby alleviate the maintenance problem considerably. This paper provides a review on the integral abutment bridge construction method and also discusses the potential benefits of using IABs. It also enumerates few limitations associated with the integral bridges and illustrates some proposed measures to mitigate these problems.
