the President JK Bridge or just the JK Bridge; crosses Lake Parano?in Bras韑ia; D.F. It is named for Juscelino Kubitschek de Oliveira; former president of Brazil; who in the late 1950s decided to build Bras韑ia as the new capital of the country. It was designed by architect Alexandre Chan and structural engineer M醨io Vila Verde.[1] The main span structure has four supporting pillars submerged under Lake Parano? and the deck weight is supported by three 200-foot tall 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 m; and it was completed at a cost of US$56.8 million (R$160 million - Brazilian Reais; current 2003).[2] The bridge has a pedestrian walkway and is accessible to bicyclists and skaters.
