Monthly Update (August 2026):
Aguas Blancas–Bermejo has had no major change at the crossing in August, although the border area remains more closely associated with security and smuggling controls than many other Argentina–Bolivia routes. The new binational bridge project is still moving through the planning stage and would eventually provide a more direct alternative to the existing crossing. For travelers using the route now, there is no new restriction or major disruption to factor in.
About this crossing
Operational Details
This checkpoint connects the Salta Province of Argentina with the Tarija Department of Bolivia. It is a major international crossing, open 24/7. The crossing is on a bridge over the Bermejo River. The facility is a hub of activity, with a constant stream of pedestrians, local traders, and international travelers, as well as a significant volume of freight traffic. The crossing can be crowded and the procedures slow, but it is a vital economic link for southern Bolivia, providing access to the Argentine road network.
A History of a Lowland Frontier
The history of this region is the history of the Gran Chaco, a vast, sparsely populated plain. The Bermejo River has long been a natural boundary. The modern border was established in the early 20th century, following the Chaco War between Bolivia and Paraguay. The towns of Aguas Blancas and Bermejo grew up as customs posts and service centers for the surrounding agricultural region, which is known for its production of sugarcane, soybeans, and citrus fruits. The discovery of oil and gas in the region has increased its strategic and economic importance.
