Triana bridge and its age

Abstract

Before the XIX century, nobody dare to construct a bridge on Guadalquivir river, from Córdoba to Sanlucar. It was, really, a great venture. In Sevilla, one of the most flourishing towns by the time in Spain, this problem was solved with a boat's bridge. That means that the technicians did not trust in the river bed. But, thanks to the fact of Sevilla’s prosperity and of the new technologies and new materials, they decided, finally, to undertake the work. The industrial use of the iron concerning communications and the success of the first suspension bridges -with span alike or higher to those herewith stated-, encouraged the technicians to jump over the one hundred and fifty meters between Sevilla and Triana . The choice of the suspension bridge was taken because it was useful to introduce other options, like this of the masonry, with Silvestre Pérez not used from the XV century, and this of iron (arcs or beams). But, no one of them solved the bed problems.
