On Tuesday, August 18, 2026, traffic expert Ernesto Arriaga reported intense congestion on the main highways entering Buenos Aires City, with slow movement at the Dellepiane link due to works by AUSA. Heading to Ezeiza, traffic is normal.

This Tuesday, August 18, 2026, traffic specialist Ernesto Arriaga reported at 08:21 AM a picture of heavy traffic on the main highways accessing the City of Buenos Aires. According to his Twitter account, there is slow movement at the link with the Dellepiane Highway due to works being carried out by AUSA (Autopistas Urbanas S.A.), the state-owned company that manages the city's urban highways.

The affected highways are:

  • Riccheri Highway
  • Jorge Newbery Highway
  • Ezeiza-Cañuelas Highway

In all cases, traffic is heavy heading towards CABA, with delays especially on the stretch connecting to the Dellepiane Highway. On the contrary, towards Ezeiza-Cañuelas, traffic is normal, according to the same report.

What is AUSA and why are there works?

AUSA (Autopistas Urbanas S.A.) is the state-owned company under the Government of the City of Buenos Aires, responsible for the construction, maintenance, and management of the city's urban highways, such as the Dellepiane, 25 de Mayo, Perito Moreno, and Frondizi highways, among others. Works on the Dellepiane Highway often cause partial closures or lane reductions, directly impacting vehicle flow towards the city center.

These types of interventions are common to improve road infrastructure, but they require drivers to plan their trips in advance and, if possible, opt for alternative routes or public transportation.

Recommendations for drivers

Given this scenario, it is recommended to:

  • Leave with extra time if traveling to CABA in the morning.
  • Consult real-time navigation apps like Google Maps or Waze to avoid the most congested areas.
  • Respect signage and detours indicated by work personnel.
  • Consider using public transportation (trains, buses, or subway) as an alternative.

Arriaga's report, known through his account @Mariafortaleza and his collaboration with media such as VTVinfo, APTTA, and Corredores Viales, is a common reference for motorists traveling through the metropolitan region.

Works on the Dellepiane Highway are expected to continue over the coming weeks, so it is recommended to stay tuned for new traffic updates.
