For this span range (70-90 m), as recent studies have proven, 1 the spanby-span construction also ensures important advantages such as continuity of the deck and a significant optimization of material consumption (in particular that of prestressing steel) because the construction stage may be almost neutral to the deck design.Until the last few years, bridges with 70 to 90 m span were typically constructed by precast solutions, metallic solutions or cantilever method. 2
