Chile reopens key border crossing with Argentina to trucks after 34-day weather closure

Chile has partially reopened its primary border crossing with Argentina, the Paso Internacional Libertadores, to cargo trucks after a prolonged 34-day closure caused by severe weather conditions. The border, a crucial link for trade and transportation between the two South American nations, had been shut since July 14 due to heavy snowfall and adverse conditions in the Andes mountains.

This closure marks the longest disruption in recent history, exceeding the 26-day closure experienced during the austral winter of 2023. Chilean authorities announced the partial resumption of traffic starting Tuesday, August 19, 2026. The reopening is under strict conditions, including limited operating hours and one-way transit, to ensure the safety of users and infrastructure.

Initially, the passage will allow trucks to travel from Argentina to Chile until Guardia Vieja on August 18, 19, and 20, between 08:00 and 20:00 Chilean time. Subsequently, from August 21 and 22, cargo transport will be permitted from Chile to Argentina until Uspallata during the same hours. These measures are in place to manage the flow of goods and mitigate the impact of the closure on supply chains.

The closure has led to significant economic consequences, with estimated losses nearing $200 million USD, according to Chilean customs authorities. Over 1,550 trucks were reportedly stranded on the Argentine side, awaiting passage. The strategic importance of this crossing is underscored by the $7.05 billion USD in cargo that transited the route in 2025, comprising essential goods like meats, vehicles, and vegetable oils. Authorities have indicated that a further announcement will be made regarding the reopening for tourism and other vehicle types once conditions permit.
