Puente Maurício Joppert, Bridge over Paraná River in São Paulo, Brazil

The Maurício Joppert Bridge is a prestressed concrete structure that crosses the Paraná River to link São Paulo state with Mato Grosso do Sul. A large embankment system was built beneath the roadway to accommodate water level changes caused by an upstream reservoir.

Built in prestressed concrete and opened at the end of 1964, the 2,550-metre bridge was Brazil's longest until the Rio-Niterói Bridge opened. It was designed and built by engineer Sergio Marques de Souza. In April 2012 the crossing was renamed from Maurício Joppert da Silva to Hélio Serejo, a writer and journalist from Nioaque who led the campaign for its construction.

The bridge carries the name of a writer whose advocacy campaign was crucial to making this crossing a reality. This naming reflects how the region honors individuals who shaped its development and regional connectivity.

The crossing is open to vehicle traffic and serves as a key route for regional transportation. Visitors can drive across or view it from nearby vantage points along the riverbanks.

The bridge was renamed in 2012 by a law signed by acting president Michel Temer. Until then it honoured Maurício Joppert da Silva, a transport minister of the 1940s who had no connection with the work; the new name belongs to Hélio Serejo, the writer and journalist from Nioaque who led the campaign for the crossing.
