Juscelino Kubitschek Bridge, also known as President JK Bridge, is an interestingly shaped steel and concrete bridge which crosses Lake Paranoá in the capital city of the Federative Republic of Brazil, Brasília. As it links the eastern shore of the lake to the center of the city, via the main avenue which is known as Monumental Axis, it is one of the most known symbols of Brazil.

The construction began in 2000, where it ended in 2002 and it was officially inaugurated on 15 December 2002. This asymmetric arch bridge which has a suspended deck is designed by the Brazilian architect Alexandre Chan with the help of the structural engineer Mário Vila Verde, and the bridge is used for vehicles, bicycles and pedestrians.

There are three spans that measure to 240 meters (790 feet), where the main span structure has four supporting pillars submerged on Lake Paranoá, however, the most notable are the three arches which are supporting the deck weight, each being 61 meters (200 feet) tall.

With the creation of these huge arches that cross the road diagonally, there are steel cables which extend down from each arch in two directions in order to support the deck. The name derives from the former president of Brazil, Juscelino Kubitschek de Oliveira, who is generally considered the main figure supporting the construction of the new capital city of the country, Brasília.
