Puente sobre el Río Picheuta, Colonial stone bridge near Uspallata, Argentina.

The Puente sobre el Río Picheuta is a colonial-era bridge of stone and mortar, built on the route ordered by Ambrosio O'Higgins toward the Viceroyalty of the Río de la Plata. It stands 21 km from Uspallata, a few metres from the line of National Route 7, near the stone ruins of an Inca tambo.

The bridge was built during colonial times and served as an important route between Chile and eastern territories. It was part of a larger network that enabled trade and movement across mountain passes.

The bridge shows how people once crossed the river to trade and travel between regions. It represents a vital connection that shaped movement and commerce in this mountain area.

The bridge stands 21 km from Uspallata, in the Las Heras department of Mendoza, just a few metres from the line of National Route 7. The stone ruins of an Incan tambo lie nearby, so the site can be seen on foot from the roadside. Mountain weather can close the pass in the cold months.

Near the bridge lie the remains of an Incan lodging station, showing how the region was used long before Spanish arrival. These archaeological traces reveal older trade routes that existed centuries before.
