It consists of seven sections of 40.6 m each and distances of the main beams is 5.80 m. The metallographic studies confirm that the structure of the bridge is made of forged iron, the chemical composition, thickness measurement, hardness was determined. The corresponding traction and Charpy tests were carried out for the exhaustive characterization of the bridge manufacturing material.
