The bridge is constituted by a central arch of filled walls, about 30 meters of free light and a light / arrow ratio of 4.86, which saves the main channel of the ravine (avenues area), and two access viaducts in each margin. The viaduct on the left bank consists of a flat section, consisting of six longitudinal beams or ribs of 14 meters of free light and three cross braces, two in the support in the stirrups and one in the center of the opening. Between the adintelado bay and the central arch is a section of four b vedas, of about four meters of light each, communicated longitudinally by means of a passage in the form of a veda also, transverse to the previous ones and of smaller height. On the right bank, adjacent to the central arch, there is another access viaduct similar to the four-sided system on the left margin, but with only two vents, and which facilitates access from the right stirrup to the central arch. The stirrups, both right and left, allow the passage from the Plaza de Santa Cruz de la Sierra and Valent n Sanz Street, respectively, to the structure of the bridge, and are constituted by mason walls to closed, with two stairways of three meters wide each on each side of them, so that they communicate the road with the lower walks located on the edge of the main channel of the ravine and that run under the access viaducts.
