Viaduct over the river of Cinyana, 96m total length, in the high-speed railway line Madrid-Zaragoza-Barcelona-French border, between Barcelona and the French border.

The static scheme is the classical in railway bridges:
– The deck is a continuous prestressed concrete hollow slab with side cantilevers, 1.34m constant depth, supported on reinforced concrete cylindrical piers and abutments.
– Longitudinal fixed point, against horizontal actions, is placed on an abutment. The deck is transversally fixed to all piers by means of pot bearings. In order to control the transversal displacements, the two cylindrical shafts that conforms each pier are braced at the bottom and at the head. Each shaft is founded on a pile of 1500mm diameter.

It is noteworthy that the viaduct is located in an area of moderate seismic activity, with basic soil acceleration a = 0.09g, this action has being decisive in the design of many elements of the structure.

The foundations of the abutments are also performed with piles 1500mm diameter.

The deck is built in one stage on falsework supported directly on the ground.
