Rain causes total closure of Marginal Tietê lanes in São Paulo

oglobo12 September 2026 at 16:58

Persistent rain caused a total closure of the lanes on Marginal Tietê, São Paulo's busiest avenue, on Saturday morning. According to information from the Traffic Engineering Company (CET) to G1, the closure occurs in the direction of Rodovia Castello Branco, at the height of the Bandeiras, Casa Verde, and Freguesia do Ó bridges. On Ponte Atílio Fontana, flooding affects both the central lanes and the express lanes.

In the direction of Ayrton Senna, Marginal Tietê has the local lane blocked at the height of Ponte Tatuapé. Marginal Pinheiros also has problems: in the direction of Castello Branco, the local lane is blocked occupying two lanes near Rua Flórida. In the direction of Interlagos, the local lane is completely blocked near Rua Andries Both, at the end of Cebolão.

CET advises drivers to avoid the affected area. According to the Center for Climate Emergency Management (CGE), the city of São Paulo registers 16 flooding points on Saturday morning, of which 10 are impassable.

Why this matters

The heavy rain that hit São Paulo this Saturday caused severe flooding on Marginal Tietê and Pinheiros, the main access roads of the city, blocking entire sections and directly affecting thousands of drivers. With 16 flooding points in the capital, the guidance is to avoid the area for those who can, since traffic jams tend to last for hours. The closure occurs after a period of intense precipitation, highlighting the vulnerability of the city's road infrastructure to extreme weather events.
