Overview
- Authorities implemented the closure on Tuesday, September 8, 2026, lowering barriers at Uspallata and Guardia Vieja at 17:00 and shutting the international tunnel at 19:00.
- Officials cited heavy snow, the risk of ice on the road and very low visibility as the reasons for the preventive measure to protect motorists and freight drivers.
- The reopening will depend on a joint Argentine–Chilean evaluation scheduled for Wednesday morning to determine whether conditions allow safe transit.
- The Paso Cristo Redentor is operating under winter hours rather than 24/7 service, and authorities urged travelers and transport companies to plan ahead and check route status before departing.
- The closure interrupts the main Argentina–Chile land corridor for people and cargo and could force delays, rerouting of freight and longer travel times for commuters and truck drivers.
