The search for new architectural shapes may lead to schemes of bridges which cannot be traced back to known and tested typologies. In these cases, a new aesthetics requires new static views. The novelty of the De Gasperi Bridge, located in Milan, consists of two steel arches diverging towards the lateral sides of the deck. Such a choice involved particular structural problems as regards to both the vertical loads and the lateral ones due to wind and earthquake. Another delicate issue was posed

The paper illustrates the criteria which led to the conception of a structural system which, while respecting the shape determined by architectural choices, activates an effective and natural force path. A synthesis of the analyses and of the experimental tests performed on the cardan joint are presented.
