Picado bridge

Provincia de Cádiz

Structural typology: BRIDGES
Date: March, 1999
Owner: Confederación Hidrográfica del Guadalquivir.
Construction: ACS
Scope: Detail Design and Technical Support

The Picado bridge has a total length of 450,00 m and a total depth of 2,30 m. Its longest span has a length of 70,00 m. The deck is made up of two steel girders. The upper concrete slab has been cast over pre-cast slabs placed over the girders. The piers consist of two piles of 1,60 m diameter and variable heights from 23,00 m to 35,00 m. The head of the piers is composite, the steel box section being used as framework and reinforcement.

The piles were placed from a boat. Once their steel heads had been put in place and the concrete cast, the steel structure of the deck was launched from the piers so that its pre-cast slabs which had also been transported by boats could be placed on top of the steel girders.
