Infrastructure maintenance and construction projects are causing various traffic disruptions across major highways in the state of São Paulo.

In mid-September, the Presidente Dutra Highway in Guarulhos scheduled nightly closures on its marginal lane between km 219 and the Cidade de Guarulhos viaduct to facilitate roadworks. These closures were set for the hours of 0:00 to 5:00 to minimize impact on peak traffic and public transport.

By October, broader infrastructure works were reported. On the Washington Luís Highway (SP-310) near Cedral, the construction of a third lane necessitated the partial closure of a U-turn device. Additionally, on the Fernão Dias Highway in Vargem, reconstruction of a pedestrian bridge following a fatal collapse in August required temporary lane closures and nighttime restrictions to facilitate the installation of new structural beams.
