São Paulo Reopens Marginal Tietê After Sinkhole Triggers 50-Kilometer Traffic Jam

Overview

• The central roadway toward the Ayrton Senna was fully blocked just after the Vila Maria bridge on Friday before crews completed repairs, and lanes reopened by 8 a.m. Saturday.
• CET reported queues exceeding 50 kilometers around 5 p.m., with backups reaching from Vila Maria to Freguesia do Ó and delays of up to 1.5 hours for drivers.
• Initial repairs done early Friday afternoon failed after another downpour, causing the asphalt to give way again and the central lanes to be reclosed.
• Sabesp stated that its water and sewage networks were not affected by the failure.
• The incident recalls a separate 2025 crater near the Atílio Fontana bridge, with those works still ongoing and slated to finish by March 2026.
