Starting July 1, 2026, the toll rates on the Anchieta (SP-150) and Imigrantes (SP-160) highways in São Paulo will be significantly altered with the introduction of free flow systems, allowing bidirectional toll collection. This change means that the current highest toll in Brazil, which is R$38.70 for cars during the descent, will be replaced by a flat rate of R$19.35 in both directions. Currently, tolls are only collected in one direction, specifically heading to the coast, and motorcycles have been exempt from fees in both directions.

The announcement was made by Raquel Carneiro, the director of the São Paulo Transport Agency (Artesp), indicating a significant restructuring in how tolls are levied on these busy highways. This move aims to streamline traffic and potentially reduce congestion by removing the asymmetric toll structure, where only one direction incurs a toll. Motorcyclists, who have historically paid no tolls at all, will continue to enjoy that exemption even with the implementation of the new system.

This transition towards a bidirectional tolling structure not only represents a shift in financial responsibilities for motorists but also raises questions about the implications on traffic flow and travel behavior. With the reduced cost to users, the expectation is that more people may choose to travel to the coast, which could lead to changes in traffic patterns and increased usage of these popular routes, especially during peak travel seasons.
