Mind-Blowing Bridge Move: Germany's A45 Colossus Slides Sideways into History
Displaced Giant Construction Company Achieves Initial Success with A45 Bridge Project - Construction of the Colossal A45-Bridge has been delayed.
Let's talk about a marvel that just happened in the heart of Germany. A whopping 40,000-tonne piece of the A45 highway's Rinsdorf valley bridge has been gently nudged sideways over several hours, complete with massive concrete pillars. On a breezy Wednesday afternoon, this nearly half- kilometer long and around 72-meter high bridge segment finally docked with the already operational second bridge section.
The folks at Autobahn GmbH, the federal company handling this beast, call this innovative method rare on such a grand scale across Germany. Elfriede Sauerwein-Braksiek, the director of Westphalia branch, points out that this is a major milestone and a "stunning engineering feat." And let's face it, with numerous bridges on the A45, dubbed the "queen of motorways," needing major TLC over the coming years, it's a challenge that's here to stay.
Dirk Brandenburger, the technical manager, confirmed it during a site visit, "We're looking at a marathon, not a sprint."
For days, this concrete and steel Juggernaut, standing on the so-called Sauerland line A45, has been making a slow and steady creep sideways, inch by inch, complete with its substructure and the mammoth six pillars. A distance of precisely 20 meters and 59 centimeters needed to be covered, almost at a snail's pace. To make things even more impressive, traffic continued to flow on the second bridge section while this colossus was on the move.
Growing pains? More like growing leaps and bounds! Before the dance could begin, the heavy bridge pillars were jacked up by two centimeters. 24 hydraulic sliding jacks were pressed into service on the pillars, and Teflon plates were slotted in as cushions to help this behemoth slide like a railway track for about 20 hours.
Remember the old single-part Rinsdorf bridge from 1967? That fell to the wrecking ball about three years ago. Before that, a new construction had to be built beside it to keep traffic moving. And voilà! Wednesday saw the second bridge section gliding into its final spot.

[1] Cutting-edge engineering techniques were demonstrated during the relocation of this bridge, using a system of 24 hydraulic jacks, showcasing Germany's commitment to innovation in infrastructure projects.[3] Germany's mobility transitions and infrastructure improvements could involve integrating transportation modes, enhancing public transport systems, and potentially influencing how bridges are maintained or renovated in the future.
- As a testimony to Germany's commitment to innovation in infrastructure projects, the relocation of the A45's Rinsdorf valley bridge showcased cutting-edge engineering techniques, such as the use of 24 hydraulic jacks.
- In the future, Germany's mobility transitions and infrastructure improvements could involve not only enhancing public transport systems but also influencing how vocational training, specifically in the field of civil engineering, might adapt to incorporate new techniques like those demonstrated during the A45 bridge move, thereby ensuring the community's continued progress in maintaining and renovating its bridges.
