Juscelino Kubitschek Bridge ({{langx|pt|Ponte Juscelino Kubitschek}}), commonly called Ponte JK ({{langx|en|JK Bridge}}), is a steel and concrete arch bridge across Lake Paranoá in Brasília, Brazil. It connects the eastern shore of the lake – where Lago Sul, Paranoá and Brasília International Airport are located – to Brasília's city center, via the Monumental Axis. Opened to traffic on December 15, 2002, its distinctive silhouette quickly became a Brasília landmark.{{cite web|author=Ministério dos Transportes |url=http://www.transportes.gov.br/bit/pontes/DF/ponte%20jk/GpJK.HTM |title=Ficha Ponte Juscelino Kubitschek - Histórico |accessdate=2008-03-08 |language=pt |url-status=dead |archiveurl=https://web.archive.org/web/20080313055423/http://www.transportes.gov.br/bit/pontes/DF/ponte%20jk/GpJK.HTM |archivedate=2008-03-13 }}
The bridge is named after President Juscelino Kubitschek, who served from 1956 to 1961 and is generally considered the main political figure to have supported the construction of the planned city of Brasília. It was designed by architect Alexandre Chan and structural engineer Mário Vila Verde.{{Cite web |url=http://www.metalica.com.br/sistema/bin/pg_dinamica.php?id_pag=656 |title=A Tercira Ponte no Lago Sul {{in lang{{!}}pt}} |access-date=2008-02-09 |archive-url=https://web.archive.org/web/20080425051914/http://www.metalica.com.br/sistema/bin/pg_dinamica.php?id_pag=656 |archive-date=2008-04-25 |url-status=dead }}

The entire structure has a total length of {{convert|1200|m|ft}}, and was completed at a cost of US$56.8 million.{{cite web|url=http://www2.correioweb.com.br/cw/EDICAO_20030107/vid_mat_070103_28.htm|author=Correio Braziliense|date=2003-01-07|title=O novo point|accessdate=2008-03-08|language=pt|archive-url=https://web.archive.org/web/20090327035421/http://www2.correioweb.com.br/cw/EDICAO_20030107/vid_mat_070103_28.htm|archive-date=2009-03-27|url-status=dead}}
