Just discovered this bridge by Sergio Musmeci (1926-81). I think it’s amazing, there’s a whole lot more words and photo’s here, as well as a pretty impressive street view image (click image below). I also quite like this Model of it.
"Musmeci is one of the most daring and transgress engineers born in the twentieth century; he was master equally of music, astronomy, aeronautics, mathematics, and philosophy, all of which informed his structures, whose shape was determined by the spatial distribution of static actions. Musmeci thought that he could reach the expression of “modernity” through science."
