The viaduct over the Turia river is one of the most remarkable works of the highspeed line in the Valencia access. As its name suggests, the main obstacle is the river itself. It is canalised by means of concrete-sloped embankments and it has a wide channel of 230 m underneath the viaduct. It is located in a consolidated suburban environment in which several services and road (V-30), railway (FGV), hydrologic and agricultural infrastructures can be found. This fact determined the position of the viaduct’s supports. Besides, it meant an additional complexity, not reflected in the definition, since every support line has a different skew. The viaduct has a total length of 572 m. Its singularity is mostly reflected in the crossing over the river, on which an integral structure, characterised by variable edge and clean and slender lines, has been built. Moreover, it is integrated into strict hydraulic conditions. Not only its design but also the execution of the post-stressed floor have been very complex due to different reasons: the changing skew of supports, the curve and reverse curve design with intermediate line, the lighting variability and its width. This made necessary to define one by one every strained cable.
