Prefabricated structure hasthe advantages of accelerating the construction, saving energy and resource, and mitigating the impact on the environment. Prefabricated structure is a reliable way to realize the industrialization of buildings. In recent years, researchers and design engineers have carried out studies on the prefabricated structure. In the field of bridge engineering, due to the rapid development of prefabricated concrete bridge structures, research on prefabricated concrete bridge structures has increased rapidly, and many new prefabricated concrete bridge structures have been applied in practical engineering. This paper presents state of the art on prefabricated concrete bridges in 2019, in views of prefabricated substructure and prefabricated superstructure to discuss the new technology, new structure and typical engineering applications in this field. From the summary of this paper, it was found that the structure of connection and seismic performance of prefabricated bridge piers are the focuses of the research in this field. It is also a key issue that hinders the construction of prefabricated bridge in high intensity region. In the prefabricated superstructure field, the connection structure between the basic prefabricated components has attracted a lot of researchers' attention. The crack resistance and fatigue performance of the connection structure need to be further improved, aiming to achieve the ‘emulative’ mechanical properties.
