The article discusses a structure, 375 m long, composed of two approach viaducts 63 and 45 m long, respectively, and the main bridge, 268 m long. The spans of the viaducts are 21 and 22,50 m long, and the seven spans of the bridge have spans varying between 34 and 42 m. The deck consists of prefabricated beams bound by the upper slab and without intermediate stiffeners. The author describes the process of construction, including the prefabrication of the beams. Taking this work as an example, he analyses the evolution of bridges of prefabricated beams and draws his conclusions on the future of this type of bridge.
