Porto de Alencastro bridge, Cable-stayed bridge over the Paranaíba River in Brazil

The Ponte Presidente Tancredo de Almeida Neves, known as the Porto de Alencastro bridge, is a cable-stayed bridge 660 m long over the Paranaíba River, on the BR-497/MGC-497 between Carneirinho (Minas Gerais) and Paranaíba (Mato Grosso do Sul). It was inaugurated on 11 October 2003 and cost R$ 124.3 million.

The bridge was planned as part of a federal highway project and completed in the early 2000s. It represented a major infrastructure initiative to improve connections between the two states.

The bridge is named after President Tancredo de Almeida Neves, as set by Law No. 10,965 of 8 November 2004. At its inauguration on 11 October 2003, the governor of Minas Gerais called it a work of national integration. It lies on the BR-497 highway between Carneirinho (MG) and Paranaíba (MS).

The bridge is passable by regular vehicles and features a wide roadway for safe crossing. It is wise to exercise caution during heavy weather or when flooding affects the river area.

The bridge is officially named Ponte Presidente Tancredo de Almeida Neves, under a law of 8 November 2004; the name Porto de Alencastro comes from the nearby Estância Turística Alencastro in Mato Grosso do Sul. It stands 660 m long on the BR-497, on the boundary between Carneirinho (MG) and Paranaíba (MS).
