Thursday, August 20, 2026, began with a weather phenomenon affecting thousands of drivers entering Buenos Aires, Argentina's capital. According to CORRESUR (Corredores Viales del Sur), the company that operates several major highways in the metropolitan area, reduced visibility due to fog is affecting three key routes: the Autopista Riccheri, the Autopista Jorge Newbery, and the Autopista Ezeiza-Cañuelas.

Highway Report Details

The alert was posted on X (formerly Twitter) by user Ernesto Arriaga at 07:34 AM local time. Here’s what the report says:

  • Autopista Riccheri: Reduced visibility due to fog.
  • Autopista Jorge Newbery: Reduced visibility due to fog.
  • Autopista Ezeiza-Cañuelas: Reduced visibility due to fog, but traffic is normal in that direction.

Meanwhile, toward Buenos Aires city (CABA), traffic is heavy, which may cause delays at the access points.

Driver Recommendations

When fog is present, safety experts recommend:

  • Reduce speed and increase the distance between vehicles.
  • Use low beams or fog lights—never high beams.
  • Avoid sudden braking or abrupt maneuvers.
  • Stay focused on the road and do not use your phone.

Fog forms when water vapor condenses in low atmospheric layers, often during early morning hours, especially near rivers or low-lying areas like those surrounding these highways in the Buenos Aires suburbs.
