Road and bridge engineering is a type of project with complicated procedures in municipal engineering, which requires a long construction period. Therefore, in the process of road and bridge engineering construction, supervision and management should be strengthened, technological innovation should be carried out around the characteristics of the project, and the construction of the engineering construction system should be strengthened to implement responsibilities. system and implement incentive policies, thereby improving the overall quality of the construction team and promoting the healthy and stable progress of bridge projects. However, roads and bridges involve a wide range and are affected by many factors, so that there are still many problems and deficiencies in construction management, which affect the further construction and improvement of my country's infrastructure. Road and bridge construction management plays an important role in national infrastructure construction. This paper is based on BIM. In the construction industry, the application of BIM technology can improve the visualization, feasibility and accuracy of architectural engineering design on the one hand, and on the other hand, it can also strengthen the communication between engineers, designers and users, which is conducive to the construction of buildings. The engineering design is carried out in an orderly manner.
