This Viaduct, number 2, on the stream of Casinyola, of 127m length, is placed 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 prestressed concrete continuous box beam, 2.64m constant depth, supported on reinforced concrete piers and abutments.
– Longitudinal fixed point, against horizontal actions, placed on an abutment. The deck is transversally fixed to all piers by means of pot bearings.

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

All foundations must be deep, with piles of 1500 mm diameter, both in piers and abutments.
The deck is constructed longitudinally in two phases, on falsework supported directly on the ground, and the concreting of cross section is done in two phases: bottom slab + webs, first phase, and top slab
