The governor of São Paulo, Tarcísio de Freitas, has signed into law a bill renaming a viaduct on the Imigrantes highway after Olinda Bonturi Bolsonaro, the mother of former president Jair Bolsonaro. The structure, located at kilometre 15 in the municipality of Diadema, will now be known as the Olinda Bolsonaro Viaduct. The legislation, introduced by state deputy Paulo Mansur of Bolsonaro's Liberal Party, was approved by the São Paulo legislative assembly in April. Mansur described the move as a "just and honourable tribute" to Olinda, who died in 2022 at the age of 94.

Olinda Bolsonaro gained national prominence during the Covid-19 pandemic when it emerged that she had received the Coronavac vaccine, a Chinese-developed immuniser that her son had repeatedly and publicly criticised. The former president, who resided in Eldorado in the Vale do Ribeira region until his adolescence, was the third of six children. The naming of the viaduct has drawn attention to the family's political legacy in São Paulo, a state where Bolsonaro remains a polarising figure. Viewed from Brasília, the gesture is seen as a consolidation of the conservative alliance between Tarcísio, a former Bolsonaro minister, and the former president's political base.

Analysts in London note that the timing of the tribute, coming years after the pandemic, underscores the enduring political capital of the Bolsonaro family name in parts of Brazil. The viaduct, a key infrastructure link in the Greater São Paulo area, now serves as a physical marker of that influence. Critics, however, point to the irony of honouring a woman whose son opposed the very vaccine she received, highlighting the contradictions that continue to shape Brazil's political landscape. The move is likely to be cited in future electoral campaigns as evidence of the ongoing alignment between state-level governance and national conservative movements.
