The most relevant results of an inspection of the Serranos and Trinidad bridges are presented, from historical-cultural, graphic-urban and technological-constructive points of view. The procedures which are considered to be more suitable for conservation and restoration of the stone materials used in the construction of these two bridges are set out, as are their structural consolidation and the architectonic-urban interventions which the valuations of these bridges as relevant urban elements in the city of Valencia are based on.
