The Anchieta-Imigrantes System (SAI) in São Paulo, Brazil, is scheduled for maintenance work from November 16 to November 22, as outlined by the concessionaire Ecovias. The maintenance includes various interventions along the highways, with specific blockades during particular hours affecting drivers' access to the capital. In particular, the Imigrantes highway will see cleaning and repairs to signage, structural safety recuperation, and environmental preservation efforts.

During this period, drivers will face specific blockages especially between 23:30 and 5:00 on selected days, where special freight loads will be redirected to use the Via Anchieta instead. Various maintenance operations such as cleaning of plates, maintenance of metal safety barriers, and the installation of new signaling will occur throughout the day and night, ensuring safety and better traffic management in the region.

These planned maintenance efforts underscore the importance of ongoing infrastructure upkeep to maintain safety and efficiency for daily commuters and transport vehicles. The timely completion of these works is essential to minimize chaos on the roads and uphold service quality within the SAI, which is critical for connecting São Paulo to neighboring regions during peak travel times.
