In mid-September 2026, Autopistas de Buenos Aires S. A. (Aubasa) introduced a new sanctioning scheme for the Buenos Aires-La Plata Highway. Drivers bypassing toll booths face fines between $228,100 and $684,300, calculated using Fixed Units (UF). To enforce these penalties, Aubasa utilizes camera systems to record vehicle details and locations.

By October 1, 2026, transportation costs in the Metropolitan Area of Buenos Aires (AMBA) saw further increases. Bus fares in both the City and Province of Buenos Aires rose by approximately 3.6% to 3.7%. Additionally, subway (subte) fares increased by 3.7%, with registered SUBE card fares reaching 1,817 pesos. Tolls for light two-axle vehicles in the City of Buenos Aires were also adjusted upward by 3.7%.

On October 8, 2026, the Ministry of Infrastructure and Public Services of the Province of Buenos Aires authorized further toll increases for roads managed by Aubasa. Routes to the Atlantic Coast (Routes 2, 11, and 74) saw increases of approximately 8.8% to 8.9%. The Buenos Aires-La Plata highway and Route 6 also received an 8.3% increase. These adjustments follow a quarterly mechanism using the Tariff Variation Coefficient (CVT), which incorporates the Registered Wage Index, the Wholesale Price Index (IPIM), and the Consumer Price Index (IPC).

Data indicates that public transport usage in the AMBA region has not returned to pre-pandemic levels. Passenger numbers for buses, trains, and subways have shown a decline of nearly 20%, attributed to factors including increased costs and reduced service frequency.
