Stress-ribbon bridges is the term that has been coined to describe structures formed by a very slender concrete deck with the shape of a catenary.

They can be designed with one or more spans and are characterized by successive and complementary smooth curves.

In the case of precast structures the deck is assembled from precast segments that are suspended on bearing cables and shifted along them to their final position.

Prestressing is applied after casting the joints between the segments to ensure sufficient rigidity of the structures.
