Affonso Penna bridge, Suspension bridge on the Goiás–Minas Gerais border, Brazil

The Affonso Penna bridge is a suspension bridge over the Paranaíba River on the border between Goiás and Minas Gerais, linking Itumbiara with the area of Araporã. It was designed and built by engineer José Luiz Mendes Diniz and is the oldest suspension bridge in Brazil. It is the main symbol of Itumbiara and a heritage asset listed by IPHAN.

Built in the early 1900s and opened in 1909, the structure marked a turning point for regional infrastructure development in central-western Brazil. It enabled new economic connections across state borders that previously had been difficult to maintain.

The bridge gave its name to Itumbiara's civic identity: it is the city's main symbol, and the 1908 construction site drew onlookers from across the region to watch the suspension cables go up. It was inaugurated on 15 November 1909, named after President Afonso Pena.

Visitors can walk or drive across the structure while observing its construction and the river landscape below. It is best to visit during daylight hours to see the details of the ironwork and wooden elements clearly.

The bridge was moved from its original site in the early 1970s, when engineers from the state power company Furnas relocated it during construction of the Itumbiara hydroelectric plant. It was repositioned to serve the workers' village in Itumbiara, with the construction site at Araporã in Minas Gerais.
