Abstract
This article describes the construction of the 5 km long viaduct, with 20 m corbels, intended to facilitate the expansion towards the north-eastern part of the city, the stretch of which was interrupted upto now by the railway line Barcelona-Port Bou. In view of the special conditions of the work and the need to maintain the traffic during the entire construction time the system of two self supporting arch centerings was chosen. Transversally the dintel is of trapezoidal cross-section with overhangs and lightened internally with circular holes. Longitudinally a solution of a continuous beam was adopted. Thus whether joints nor anchorages were required. The foundation rests directly on footings. The construction has been carried out in prestressed concrete and can be divided into three basic parts: entry on the Barcelona side; passenger station; passenger station-rio Ter.

Summary
La línea del ferrocarril Barcelona-Port Bou a su paso por Gerona deja en el momento actual la ciudad cortada, entorpeciendo su expansión hacia el NE. Por esta razón el Ministerio de Obras Públicas estudió las posibles soluciones para evitar este problema y llegó a la conclusión que la solución más adecuada era la elevación de la vía a su paso por Gerona, conservando aproximadamente el mismo emplazamiento tanto para la vía como para la estación, dejando la superficie a nivel totalmente libre para circulación y comunicaciones de la ciudad Este viaducto llegará hasta el borde mismo del río, donde empieza el puente sobre el Ter y su acceso desde la otra margen, que actualmente la Renfe está ampliando para doble vía, pero con solución distinta a la de este viaducto
