Overview
- The crossing is only operating until 14:00 Thursday, with traffic stopped at Uspallata from 12:00 for all vehicles in both directions.
- Authorities issued the preventive daytime interruption because conditions in the high Andes do not guarantee safe transit, according to official notices.
- A separate maintenance window from 20:00 to 23:00 will fully suspend vehicle flow while crews service tunnel video surveillance and wifi systems.
- The cut for maintenance applies to both directions and to all vehicle types for the duration of the work, officials said.
- The national weather service forecasts subzero lows with rain and snow in coming days, and travelers are urged to plan ahead and check official channels as 24‑hour operations will resume only if conditions allow.
