The Puente de la Mujer bridge in Buenos Aires, Argentina was designed by Spanish architect Santiago Calatrava. Completed in 2001, it is a cantilever cable-stayed bridge with an asymmetrical design representing a couple dancing tango. Notable features include a single stabilizing pylon at a 45 degree angle, and a central rotating section that opens 90 degrees to allow water traffic to pass through, taking less than two minutes to open. At 170 meters long with a central rotating span of 102 meters, it is one of Calatrava's few works in South America.
