. According to business executive Bob Schmetterer, the bridge was not part of the original Puerto Madero project. Jorge Heymann, a Buenos Aires advertising executive, had been hired to develop an advertising campaign for Puerto Madero, but his analysis showed that the biggest challenge of the site was access, not public awareness. A landmark footbridge, Heymann suggested, while certainly more costly than an initial advertising campaign would have been, would be more practical and lasting. The developer agreed with the assessment, and he built the structure.Bob Schmetterer, ''Leap: a revolution in creative business strategy'', John Wiley and Sons, 2003, p. 148-151.
