The use of integral abutments in bridges goes back many years to the late 1930’s in the United States. Over the years, integral bridges became more popular as more and more states built those bridges and more engineers became familiar with their design and construction. These bridges are being built in Europe since the 1980’s. An integral abutment bridge acts as a frame structure with a continuity connection between the superstructure and the substructure. The substructure is typically an integral cap supported on single row of piles that provides flexibility to accommodate thermal loads and displacements. The main advantage of integral abutment bridges is that they are built without expansion joints which eliminates maintenance costs and reduces construction costs. Because of the interaction between the soil and the integral abutment under the applied loads and the cyclic nature of thermal loads, the analysis and design of integral abutment bridges can be, in some cases, challenging especially when the designs falls outside the geometrical limits set by existing standards. This overview focus on field performance data reported in the literature and interpretation of this data. IT also highlights the needs for more test data during construction and for long term performance under cyclic thermal movements. Deck replacement requirements in integral abutments were investigated using analytical models and recommendations for deck replacement preparations are provided.  \nKeywords: Integral abutment, soil-structure Interaction, monolithic, stiffness  \n1. Introduction  \nIntegral abutment bridges became a popular choice of bridge construction for state DOT’s as engineers gained more experience in their design and construction and more information was disseminated to the engineering community such as the 2013 TRBSHRP 2 Report S2-R19A-RW-2 [1] and other documents as well as publication of more research on the subject. Their acceptance stems from the fact that no expansion joints or bearings exist within the bridge or at its ends thus reducing construction  \n∗Corresponding author.

While these are significant advantages of integral abutment bridges, there are some challenges in their design such as criteria for maximum length and maximum skew, torsional forces in horizontally integral curved bridges, connection to the approach slabs, connections to wing walls in highly skewed abutments, the interaction between the abutment walls and the soil behind them, and the potential of ratcheting of the backfill after many cycles or bridge expansion and contraction.
