Successful installation of the new railway viaduct in Rüsselsheim am Main

 

On 27 February 2026, the new railway viaduct was installed in Rüsselsheim am Main.

The two trough bridges, each approximately 25.00 m long and around 5.50 m wide, were transported from the manufacturing site in Darmstadt to the installation site on Bonner Straße during the night of 26 to 27 February 2026. The footway structures and the railings had already been pre-assembled at the factory, so that only the lifting of the structures was required on site.

The steel superstructures, each weighing approximately 90 tonnes, were moved into their final position using a project-specific assembly girder (auxiliary structure). The lifting was carried out using a mobile crane in a so-called single-lift procedure, during which the superstructures were set down onto the abutment benches manufactured by Adolf-Lupp GmbH.

Within around six hours, both trough structures were hoisted into place, aligned correctly and secured in their final position, allowing subsequent construction work to continue without delay.

Despite the confined space, the assembly team from Donges SteelTec GmbH succeeded in precisely positioning the steel superstructures. The existing torsion beams and the cable routes running beneath them posed a particular challenge, as they significantly restricted the available working space.

 

Donges SteelTec GmbH is delighted to continue driving forward the transport transition in infrastructure, both regionally and in the area surrounding our Darmstadt site, through smaller projects as well.
