Revolutionary bridge shift on the A45: Engineering in action!

Revolutionary bridge shift on the A45: Engineering in action!

Rinsdorf, Deutschland - On June 4, 2025, Germany experienced an impressive engineering project: The new part of the valley bridge Rinsdorf on the A45 in the Siegerland was successfully postponed. The massive construction, which weighs around 40,000 tons, is almost 500 meters long and 72 meters high. The shift took place on Wednesday, whereby the bridge part was scheduled for the second substructure that was already put into operation. Autobahn GmbH described the process as innovative and nationwide unique in this size, since both the bridge part and the pillars were postponed, which has not yet been realized in Germany.

like FAZ.NET , the cross-range of the bridge began on Tuesday. This technically complex measure extended over a distance of 20 meters and 59 centimeters and lasted a total of 20 hours. During the entire process, traffic on the second sub -building was still able to flow, which underlines the special planning and coordination of the engineers.

innovative technology in bridge construction

Elfriede Sauerwein-Braksiek, director of the Westphalia branch, emphasized the engineering performance and emphasized the need for further renovations of the bridges on the A45. Dirk Brandenburger, technical managing director, described the mammoth task, which could still take decades. The shift procedure required the use of 24 hydraulic shock presses and teflon plates to minimize friction, and the construction field had to be comprehensively locked up for safety reasons.

The autobahn.de notes that the previous work was raised by two centers, as well as the extensive planning for several years. The old one -piece bridge from 1967, which was blown up three years ago, had to make room for the new building, which was built next to the old bridge.

The Federal Running Strasse, which also includes the A45, plays a central role in the mobility of people and goods and is crucial for economic growth in Germany. According to uni-due.de , almost 50 % of all driving performance are handled through federal streams, which is why the maintenance and renovation of the road network has top priority.

The bridge itself was blown up in February 2022 and the new building has lasted since the groundbreaking ceremony in September 2017 until the final shift, which could be followed as a live stream on YouTube. The engineers expect the new building to sustainably improve traffic flows in the region.

summarized this project not only a technological progress in bridge construction, but also a significant step in modernizing the transport infrastructure in Germany.
