| Abstract: | With the Ermi River Bridge as a practical example, which is on a curved line and intersects a highway, the box girder-pre-casting and erecting processes are presented in the paper, with stress placed on the key techniques for the transportation of girders on the curved line, the moving forward of the bridge erector and the erection of the obliquely intersecting girders, as well as the lowering of girders. The project may serve as a useful reference for other similar projects. |

| Keywords: | obliquely-intersecting girders on a curved line box girder pre-cast erection assembled multipurpose-member bridge erector |
