Project Description

Degree of Freedom verified the capacity for increased loads and designed the precast concrete segments to widen the deck of the century-old masonry arch bridge in Gata de Gorgos, Alicante.

In 1915, as part of the new railway line from Alicante to Dénia, the masonry bridge over the river Gorgos was built. It consisted of 8 arches with diameters between 10m and 20m, and a 4 m width. As part of the renovation project of the Line 9 between Teulada and Gata de Gorgos, Degree of Freedom has performed the verification of the structure for the new traffic loads, as well as the design for the rehabilitation and widening of the platform. The latter was carried out by the installation of 7,5m width concrete precast concrete segments over the existing masonry deck. The precast concrete segments are 2,5m long and have two cantilevers to create walkways at each side outside the clearance gauge. Prior to this the original structure had to be cleaned, the mortar reinstated, and the top stones strengthened and stiched from side to side.
