Donges moves new cable-stayed arch bridge into final position for Deutsche Bahn. Milestone reached in the infrastructure project in Bad Camberg.

 

On 31 March 2026, the new railway viaduct was successfully moved into its final position in Erbach (Bad Camberg).

The approximately 62.5 m long and 13.5 m wide arch-truss structure, with a total weight of around 800 tonnes, was constructed as part of the Bad Camberg–Erbach–Würges bypass. The installation took place during a temporary track closure in the early hours of the morning and was completed on schedule.

Using self-propelled modular transporters (SPMTs), the fully pre-assembled bridge was picked up from the assembly site, hydraulically lifted and moved with millimetre precision over the abutments into its final position. The soft ground posed a particular challenge, which was addressed by using load-distributing steel plates along the route.

The successful implementation was only possible thanks to the close cooperation between the Donges SteelTec / Albert Weil consortium and the client, as well as the precise preparation of the installation process.

The steel structure consists of a total of 40 prefabricated individual components, which were manufactured at the Donges plant in Darmstadt and subsequently pre-assembled and welded on site.

Yet another fine example of precise engineering and coordinated construction processes in infrastructure engineering.
