Abstract:  This paper arises from the intention by the Town Hall of Lujan de Cuyo, declared heritage sites of the old Iron Bridge, which is in full use to be an important means of communication for vehicles up to 4000 kg. Thus, the relevant historical research of the origin of the bridge in the Municipal Archives were performed, with installation in 1898 decreed by President Roca. It consists of seven sections of 40.6 m each and the center to center distance of the main beams is 5.80 m. Metallographic studies confirm that the bridge structure is wrought iron or hot rolling, and the chemical composition was determined, besides thickness measurement, hardness. Tensile tests corresponding to the complete characterization of the manufacturing material of the bridge were made. His survey allowed to observe their condition, corrosive state assessment.
