This is a bridge of Baroque design, which was built between 1718 and 1732 by the architect Pedro de Ribera. It joins both banks of the Manzanares River, linking the Pirámides roundabout on the east bank with the Marqués de Vadillo roundabout on the west bank. Among others, it consists of a central part formed by nine semicircular arches with solid buttresses and drums that end in balconies. In addition, the deck is 4.95 m wide.

In the central area, there are two niches or temples decorated with Churrigueresque elements and containing the limestone statues of the patron saints of Madrid, San Isidro Labrador and Santa María de la Cabeza, made in 1723 by the sculptor Juan Alonso Villabrille y Ron with the collaboration of Luis Salvador Carmona.

At each end of the deck there are ramps that connect with each of the banks. On the side corresponding to the Pirámides roundabout, two other ramps, transversal to the bridge, formerly gave access to the washing places and vegetable gardens located on the river bank. The obelisks included in the 19th century by the architect Francisco Javier de Mariategui at the northern end are also striking, as are the two fountains designed by Ribera in the part closest to the city centre.

Curiously enough, the purpose of its creation responds to the need detected by Philip IV to link the town of Madrid with the road to Toledo by means of a bridge over the Manzanares River.
