The bridge was built in 1857 at the initiative of local neighbor Cipriano Martinez.
It replaced an earlier ferry crossing system that existed at the same point on the river.
The structure underwent a major restoration project in the late 20th century to preserve its original materials.
The Areco River, which flows beneath, is a key geographical feature that shaped the layout of the town's historic core.
It was declared a National Historic Monument by the Argentine government to protect its cultural significance.
The Puente Viejo (Old Bridge) is a historic structure spanning the Areco River in San Antonio de Areco, Buenos Aires Province. Constructed in the mid-19th century, it served as a vital crossing point for livestock and commerce during the region's formative years. The bridge features a characteristic colonial architectural style and remains an iconic symbol of the town's gaucho heritage. Today, the surrounding riverbanks are maintained as a public green space frequently used for recreational activities. It connects the historic town center with the La Blanqueada area. The structure is built from bricks and lime mortar, reflecting the engineering techniques of its era. Visitors often gather here for evening walks and to view the sunset over the water.

Bring a picnic blanket to use the grassy banks along the river for a traditional Argentine-style outdoor meal.
Combine your visit with a walk to the nearby La Blanqueada museum, located just across the bridge.
Carry mosquito repellent, especially if visiting during the humid summer months or near dusk.
Do not attempt to cross the bridge by car, as it is restricted to pedestrian use.
