Hochstraße Süd - Ludwigshafen
Short description
The new bridge serves as a replacement for the Pilzhochstraße between Weißer Hochstraße and Konrad-Adenauer-Brücke. It offers more safety and less road noise with the same bridge width.
Thanks to our motivated staff and our flexibility, it was possible to build 6 instead of the originally planned 5 construction phases in the 2024 calendar year.
The project
The main supporting structures of the separate superstructures (in the direction of Mannheim and Bad Dürkheim) are generally wide, single-webbed slab beams in prestressed concrete construction. The width of the webs varies depending on the width of the road. The bridge is located in an inner-city area with a limited construction area. Constraints result from the inner city location as well as from the technical, scheduling and construction process-related interfaces. The bridge has a length of over 520 m, runs parallel to railroad tracks and crosses various streetcar lines.
The tendons are prefabricated in our factory in Bobenheim-Roxheim, are delivered to the construction site and can then be installed quickly and efficiently on site. Just one week after the concreting of the individual construction sections, the tendons are prestressed to the required strength and then grouted.
