Mystery Bridge Nr. 158: The Missing Bridge at Hemenswarft

Approximately one kilometer east of Südwesthörn along the North Sea Coast in Schleswig-Holstein is a missing bridge. The bridge is located behind the vacation home complex , Haus Hemenswarft, a combination of vacation home complex with amneties, including playground. One can see the missing piers on both sides of the stream Alte Sielzug, a waterway that empties into the North Sea but is regulated by a nearby dam at Südwesthörn. Even from the bike trail Am Seedeich, one can see the piers.

I tried to focus in on one of the piers with my Canon EOS250 camera, and it reveals that both piers were narrow, which means the bridge was probably used for pedestrians and cyclists. The width of the bridge is most likely between two and three meters. This means the most likely bet is that a beam bridge had existed because this bridge type fulfills the criteria of accommodating peds and bikers while maintaining the maximum width of the bridge. It is unlikely that other bridge types, such as arch, truss or even a covered bridge would fit over the pier unless there were additional angle supports supporting the (extended) deck. A suspension bridge or even a cable-stayed bridge would be pushing the limit for one could construct a tower and support the decking with cables, but these towers would have to be narrow but not in the way that a person cannot cross the bridge. Furthermore, it would have to accommodate the high winds and the rising and lowering tides- both are typical of the North Sea.

Nevertheless, the type of bridge is the first of the questions we have about this crossing. Even though the piers appear to be 40-50 years old, judging by their modern shapes and the material of concrete used, the question focuses on when exactly was the bridge built and by whom. And last but not least, why was the bridge removed? Because the waters of the Alte Sielzug, like the North Sea, is really salty, there is a chance that the salt ate away at the materials used for the bridge, thus making the bridge too dangerous to use because of its potential of structural failure, resulting in its removal. The road leading to the bridge has been abandoned for some time, primarily because of this route that is now being used.

To sum up:

  1. Which type of bridge was this built?
  2. When was the bridge built and by whom?
  3. What were the dimensions of the bridge?
  4. When and why way the bridge removed.

And for that, you now have the podium and know what to do in case you know more about this bridge. 🙂 Good luck and happy bridgehunting, folks.
