An unusual museum exhibition due to the considerable size of the object. The old bridge span was left as a souvenir of the old technology, instead of being sent to a steelworks and melted down into something new. At the same time, it was repainted in a completely different color than when it was in use. You can see it in one of the photos I attached.
The second life of the bridge concerns not only the old span, but also the new railway bridge located next to it, made of "recycled" spans brought from Krakow. Economic efficiency worth repeating - something is no longer useful in one part of the country, but is useful in another, less demanding one.
