Puente de la Mujer
Tango dancers inspired the sweeping asymmetrical lines of Valencian architect Santiago Calatrava's design for the pedestrian-only "Women's Bridge." Puerto Madero's street names pay homage to famous Argentine women, hence the bridge's name. (Ironically its most visible part—a soaring 128-foot arm—represents the man of a couple in mid-tango.) The US$6-million structure was made in Spain and paid for by local businessman Alberto L. González, one of the brains behind Puerto Madero's redevelopment; he was also responsible for building the Hilton Hotel here. Twenty engines rotate the bridge to allow ships to pass through.
