It's a historic railroad bridge that has not been used for a while, steel construction, and it has been taken apart and put together many times before, sometimes for maintenance. IIRC the current mayor promised the people not to do it again, and then came Bezos, and then they didn't take it apart, they installed the yacht's masts downstream instead.
This is the bridge in question: https://en.wikipedia.org/wiki/De_Hef
Thank fuck tho, it will keep electric waste down, and I feel we are starting to figure out you don't need to spec your game to the newest graphics card for it to be fun.
