The new pedestrian and pivoting bridge was built in Dock 3, in Puerto Madero neighborhood (at the level of Avenida de Mayo). It is the first work that the architect and engineer Santiago Calatrava built in Latin America. This bridge is 160 m. long by 5 m. wide. The metallic arm, 39 m. high, can be seen from Leandro N. Alem avenue. The bridge is prepared to move up whenever a ship has to get through. The pivoting mechanism is one of the biggest in the world. It has 20 electric and computerized motors in the main axle.

This bridge was granted to the City of Buenos Aires by the businessman Alberto L. González. It has been an investment of 6 million dollars. Built in Spain, its different fragments were then shipped to Buenos Aires.
The plastic interpretation of the work is a couple dancing tango, where the white mast represents the man and the curved profile of the bridge is the woman.
