It links the southern part of the lake, and St. Sebastian Paranoá the Pilot Plan (or the central and original part of the city), through the Monumental Axis. Inaugurated on December 15, 2002, the structure of the bridge has a total length of 1,200 metres (3,900 ft), a width of 24 metres (79 ft) and two carriageways with three lanes in each direction, two walkways on the sides for cyclists and pedestrians 1.5 metres (4.9 ft) wide, and three spans of 240 metres (790 ft). It is named for Juscelino Kubitschek de Oliveira, former president of Brazil, who in the late 1950s decided to build Brasília as the new capital of the country. It was designed by architect Alexandre Chan and structural engineer Mário Vila Verde. The main span structure has four supporting pillars submerged under Lake Paranoá, and the deck weight is supported by three 200-foot-tall (61 m) asymmetrical steel arches that crisscross diagonally. The decks are suspended by steel cables alternating at each side of the deck, interlacing in some kind of twisted plane (parabolic like). The entire structure has a total length of 1,200 metres (3,900 ft), and it was completed at a cost of US$56.8 million (R$160 million - Brazilian Reais, current 2003). The bridge has a pedestrian walkway and is accessible to bicyclists </i> <a href="http://en.wikipedia.org/wiki/Juscelino_Kubitschek_bridge" rel="nofollow">Wikipedia</a>
