The bridge is part of a section located in the Municipality of Alcala de Guadaira, with an approximate length of 2,900 m. It is the continuation of the Zacatín Roads that collects traffic from the A-92 from the SE-410 to Highway A-392 (Alcalá de Guadaira “Two Sisters”).
From the standpoint of quality control and innovation in materials, The Keeper of the Castle Bridge was the first bridge built in Spain with self-compacting structural concrete (Hormigón Autocompactante HAC). During the construction of the bridge the HAC was in the pre-approval stage in Spain. Therefore, our technicians were actively involved in this project. The experience acquired has been the subject of numerous technical publications and lectures at Universities and Technology Centers nationwide.
