| Abstract: |
The existing six-lane highway bridge, which crosses the Rhine River between Duisburg-Neuenkamp and Homberg, was originally opened to traffic in 1970. Due to increased traffic loads and severe fatigue damage it now needs to be replaced. The new design consists of two similar cable-stayed steel superstructures, each carrying four lanes. It has an overall length of 802 m, an overall width of almost 70 m, pylons of 90 m in height, and a central span of 380 m. The installation of the superstructure comprises incremental launching of the approaches, crane assembly of the pylons, and the cantilevered assembly method of the central span. Additionally, the requirement to maintain vehicular traffic on the A40 highway during the construction phase demands transversal launching of the southern bridge structure by 14.4 m after completion. This paper covers the design and implementation of the installation works of the steel structures on site. |
