In the 18th century two further attempts to repair the bridge failed, in 1730 and 1760–70. The latter plan of the military engineer José García Galiano included a complete reconstruction with three large-span segmental arches. The planning sketch shows that already at that time the remaining arches were limited to the right bank, a finding confirmed by the drawing of Fernando Rodríguez from 1797 and engravings in Alexandre de Labordes' "Voyage pittoresque de l'Espagne" a few years later. The reconstruction sketch produced by Rodriguez (see diagram below) shows the profile of the bridge, rising evenly and dominated by three central arches in the centre of the river. These arches are flanked by a further nine segmental arches on both sides. The symmetry of the arches suggests that, in lieu of the fortification on the right bank viewed upstream, there might have been another segmental arch in Roman times.
