Monterrey Reopens Morones Prieto Express Lane After Line 4 Damage Repairs

Overnight remediation by the contractor won municipal approval after inspectors documented unstable, uncompacted fill.

Overview

  • Traffic returned to normal Friday on the left express lane of Avenida Morones Prieto following a six‑day closure tied to Line 4 construction work.
  • Municipal authorities formalized the damage in a supervision act attended by city officials, state mobility representatives, and the construction firm Magna.
  • City inspectors previously halted an attempted reopening that lacked full reconstruction, specifying the need for excavation, layered compaction, and asphalt replacement.
  • Inspections recorded cracks up to three centimeters that formed without vehicle load, indicating an unstable base and risk of further subsidence.
  • Mayor Adrián de la Garza said the fix should have taken two days, as the state pressed to restore circulation, while local commentary cast the episode as a political clash.
