The Cristo Redentor International Pass, a vital link between Argentina and Chile, has faced a cycle of prolonged closures and phased reopenings. Following a historic 34-day closure caused by extreme winter weather, the pass underwent a progressive reopening restricted to land cargo. Between August 18 and August 22, cargo trucks were permitted to travel in alternating directions during specific daytime hours, with priority given to documented vehicles in the Uspallata parking lot. Tourism and private passenger transit remained suspended to manage the backlog. The extended closure resulted in significant economic impacts, with some estimates suggesting losses of approximately US$ 200 million. Despite these efforts to normalize trade, the pass remains vulnerable to meteorological instability.

This period of stability was short-lived. On Tuesday, September 2, authorities implemented a two-stage closure of the Cristo Redentor International Tunnel due to severe weather and heavy snowfall. Barriers at the Uspallata control point in Argentina and the Guardia Vieja point in Chile were scheduled to close at 17:00, with a full tunnel closure following at 19:00. This preventive measure was taken to mitigate risks from snow accumulation, ice, and low visibility.
