The viaduct over the Pla dels Caboters, is in the High Speed Line Madrid-Zaragoza-Barcelona-French border, between Barcelona and the French border. Its total length is 442m, distributed in spans of : 33m + 8x47m +33m.

The static scheme is the classical for railway bridges:

– Prestressed concrete continuous box beam (3.24m constant height) 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 has being decisive in the design of many elements of the structure.

Foundations of piers and abutments are directly on footings.

The deck has been constructed by the span by span method on falsework directly supported on the ground. The cross section has been concreted in two phases
