Overview
- Initial works at Universidad will focus on garages, workshops and parking from late January or early February, largely at night, with this phase planned to finish before the June 11 World Cup kickoff.
- Major tunnel interventions and any extended station closures are scheduled to start in mid-July 2026 after the FIFA World Cup matches in the city.
- Authorities outlined a staged program with temporary segment closures across the Indios Verdes–Universidad corridor, drawing on lessons from the Line 1 upgrade.
- Officials cited aging infrastructure and subsidence, especially between Potrero and Indios Verdes, as drivers for the overhaul and current speed restrictions.
- The project is expected to span about two years of work, with completion targeted for late 2028.
