Mexico City Says Line 12 Beam Gap Poses No Risk After Viral Photos

City engineers classify the visible gap as a construction joint posing no operational risk.

Overview

  • Images shared on social media showed a separation between two beams on the elevated stretch between Lomas Estrella and San Andrés Tomatlán.
  • The Metro authority said the condition has been documented since 2021, and specialist engineers found the beams fully supported with service unaffected.
  • Officials located the feature at column LOE-14, about 170 meters from Lomas Estrella, and said stains in the area are from rainwater rather than a fissure.
  • Residents and PAN lawmakers demanded independent forensic reviews and public reporting, citing distrust following the 2021 collapse that left 26 dead.
  • City agencies said elevated structures undergo permanent monitoring and routine preventive and corrective maintenance.
