Overview
- Authorities ordered a preventive halt to cross-border traffic on Friday until further notice, citing unsafe high-mountain conditions.
- Control points at Uspallata in Argentina and Guardia Vieja in Chile began staged traffic cuts ahead of the full shutdown to keep vehicles out of the high pass.
- Forecasts call for rain turning to snow Friday, continued snowfall Saturday, and clearing on Sunday with temperatures roughly between -6°C and 6°C.
- Reopening will follow an improvement in weather and on-site checks of the roadway by national road agencies from both countries.
- Travelers were urged to verify the pass status on official Vialidad channels and to delay trips, as the closure affects both tourism and freight on the Andes’ main corridor.
