Bridge maintenance should be performed on the basis of the shape and specifications data of the bridge in operation, but the paper and computerized drawings of 2D and 3D models are used in the field. Therefore, it is very difficult if not impossible to modify the specifications that change with the inspection cycle. Recently, advanced optical technology have enabled the acquisition of 3D digital data (LiDAR) scanned actual structure, overcoming the limitations that may arise from the maintenance of existing drawing bases. This paper will introduce bridge that utilizes digital pseudo-reality(DPR)based bridge maintenance system using 3D digital data obtained by scanning a bridge currently in operation.
