Puente de la Mujer
Puente de la Mujer (Spanish for "Women's Bridge") is a rotating footbridge for Dock 3 of the Puerto Madero commercial district of Buenos Aires, Argentina. It is of the Cantilever spar cable-stayed bridge type and is also a swing bridge, but somewhat unusual in its asymmetrical arrangement. It has a single mast with cables suspending a portion of the bridge which rotates 90 degrees in order to allow water traffic to pass. When it swings to allow watercraft passage, the far end comes to a resting point on a stabilizing pylon.
==History==
Designed by the Spanish architect Santiago Calatrava on a plan very similar to a 250-metre bridge over the Guadalquivir River in Seville, Spain (1992) and a 213-metre bridge over the Sacramento River in Redding, California (2004), it has a forward-, rather than a reverse-angled cantilever, as is seen in those bridges. Started in 1998, it was inaugurated on December 20, 2001, and is the only one of Calatrava's works in Latin America. The architect has described the design as a synthesis of the image of a couple dancing the tango.
The 170-metre pedestrian bridge weighs 800 tonnes, is 6.20 m wide and is divided into two fixed portions, 25 m and 32.50 m long respectively, and a middle section of 102.5 m that rotates on a white concrete pylon, allowing vessels to pass in less than two minutes. This central section is supported by a steel "needle" with a concrete core, about 34 m high. The "needle," inclined at a 39° angle, anchors suspension cables which support the central span. A computer system at the eastern end of the bridge operates the turning mechanism when required.
