On Sunday, September 20, 2026, anyone who needs to travel around the Interlagos racetrack should allow extra time and pay close attention to traffic signs and instructions from São Paulo's Traffic Engineering Company, CET. The weekend traffic operation may lead to operational roadblocks and access changes depending on vehicle and pedestrian flows.
What is confirmed for this Sunday
CET is maintaining traffic monitoring operations for events across the city this weekend. In Interlagos, the practical guidance is to treat the area around the José Carlos Pace Municipal Racetrack as a zone where temporary traffic controls and operational roadblocks may be introduced. However, a dedicated September 20 notice containing a complete road-by-road list and today's specific activation times was not found among the indexed official CET pages checked for this article.
This matters because Interlagos traffic plans vary according to the size and schedule of each event. On September 12, for example, CET monitored the area from 8 a.m. to 6 p.m. for Endurance Brasil. On September 13, for Summer Beats, monitoring ran from 5 a.m. to 10 p.m., with entry roadblocks starting at 5 a.m. and an exit operation beginning at 7 p.m. Those times are useful only as examples of how CET organizes traffic and must not be automatically applied to this Sunday.
Roads to watch around Interlagos
In the most recent official racetrack operations, CET concentrated monitoring on corridors that form the main access routes to the complex. They included:
- Avenida Interlagos;
- Avenida Senador Teotônio Vilela;
- Rua Jaquirana and Rua do Autódromo;
- Praça Enzo Ferrari, Praça Jacob Dubena and Praça Moscou;
- Avenida do Jangadeiro and Avenida Jacinto Júlio;
- Avenida Feliciano Correia and Rua Plínio Schmidt.
The fact that these roads appeared in recent operations does not mean they are all closed today. It shows where drivers should expect a higher likelihood of access controls, diversions or temporary blocks when an event is taking place at the racetrack.
Times: why you should check before leaving
| Information | Status |
|---|---|
| Sunday, September 20, 2026 | A traffic operation around Interlagos has been reported for the weekend, with possible operational roadblocks. |
| Complete list of today's roadblocks | No specific indexed official notice with every September 20 road segment and activation time was found in the pages checked. |
| Recent reference | Earlier September operations used different time windows depending on the event, so there is no reliable standard timetable to apply to this Sunday. |
Drivers should therefore check conditions shortly before departure, obey cones, barriers and traffic officers, and avoid relying on a single route into the area.
How to reach the racetrack area
The José Carlos Pace Municipal Racetrack is at Avenida Senador Teotônio Vilela, 261. CET notices list the main access corridors as Avenida Interlagos, Avenida Atlântica, Avenida das Nações Unidas, Avenida do Rio Bonito, Avenida do Jangadeiro, Avenida Senador Teotônio Vilela and Avenida Jacinto Júlio, as well as the Jurubatuba and Socorro bridges.
For travelers who can use public transportation, CET routinely recommends it on event days. Recent CET notices place Autódromo train station about 800 meters from the circuit, allowing visitors to avoid part of the concentrated vehicle traffic immediately around the gates.
Drivers, residents, taxis and ride-hailing
In recent operations, residents of restricted streets were allowed through after identifying themselves to traffic officers at roadblock points. Because rules can change from one event to another, residents should confirm the procedure on site rather than assume that the same access rule applies at every roadblock today.
Recent events have also used designated taxi areas and meeting points for private or ride-hailing vehicles. Those locations are set for each specific traffic plan, so addresses from a previous event should not be reused without current confirmation.
CET recommendations to reduce disruption
- Use public transportation whenever practical.
- Follow road signs and instructions from CET and Military Police officers.
- Do not park double-file, on sidewalks, medians, lowered curbs, property setbacks or public squares.
- Do not accept directions to park in prohibited places.
- If you need information, stop only in a safe place without obstructing traffic.
- Plan an alternative route before reaching the racetrack perimeter.
How to confirm conditions before traveling
For traffic information, incidents, towing, complaints and guidance, CET directs the public to SP156. Travelers heading to Interlagos should also follow on-site signs and officer instructions because operational blocks can be activated or removed according to crowd movement.
The key point for this Sunday is straightforward: traveling around Interlagos requires route planning, while exact road segments and times should be confirmed on the day. Recent operations show which corridors often receive traffic controls, but they do not establish that every one of those roads will be blocked on September 20.
