Inaugurated on December 15, 2002, the structure of the bridge has a total traversing length of 1,200 meters, 24 meters wide with two lanes, each with three lanes, two walkways on the sides for use by cyclists and pedestrians with a 5 meters in width and length of spans of 720 meters.
The structure of the bridge has to support four pillars submerged in Lake Paranoá and three spans of 240 meters are supported by three arches asymmetric and located in different planes, with tensioned steel cables placed in a cross shape, which geometrically means that the cables parabolic form a plan. With its asymmetrical arches, the structure of three arches, inspired "by the movement of a stone bouncing on the water surface," [2] is unique in the world, comparable in form but not in the structural system, such as the Aquarium of the public walkway Port of Nagoya, Japan [3] Initially budgeted in 1998 for $ 40 million, it is estimated that the total construction cost was $ 160 million. [4] Its architectural beauty resulted in structural design of a highly but despite the additional cost, the Federal District Government considered it vital that the bridge was at the level of monumentality that Brasilia was designed.
Inaugurated on December 15, 2002, [5] over the bridge quickly became an icon in Brasilia stamped postcard, especially at night when its theatricality is further highlighted. Due to aesthetic and environmental harmony of the JK Bridge, the architect's work, Alexander Chan, received the 2003 Gustav Lindenthal Medal, awarded by the Engineers Society of Pennsylvania, United States [6]. Because of this award, the structure was known locally as the most beautiful bridge in the world.
