Overview

• Authorities said the leak began Wednesday morning at Avenida Juan B. Justo and Paraguay after a repaving machine struck a gas pipe.
• Firefighters, SAME, police and Metrogas set up a safety perimeter, evacuated nearby premises and reported no injuries as the situation was brought under control.
• Metrogas executed a prensado maneuver to cut flow upstream and isolate the break, with definitive repairs ongoing because the steel line is encased.
• Traffic remains closed on Juan B. Justo from Santa Fe to Guatemala with bus detours in place, and Trenes Argentinos limited San Martín line service to avoid Palermo station.
• Work sources and Metrogas gave conflicting accounts of the pipe’s burial depth—about 30 cm versus 1.4–2 m—raising questions about procedures and responsibility.
