Old Pueyrredón Bridge, Road bridge in Avellaneda Partido, Argentina
Old Pueyrredón Bridge is a steel structure spanning the Riachuelo River and connecting the two districts by road and foot traffic. The construction displays early industrial-era engineering with clear structural lines and functional design.
Built in 1931, it replaced wooden bridges that had existed since 1791. This shift from timber to steel shows how transportation needs evolved as both sides of the river became more densely populated and industrialized.
The bridge reflects how Buenos Aires and Avellaneda grew as connected industrial centers during the 20th century. You can see this connection in the structure itself and its role linking two important urban areas.
The bridge is open to both vehicle and pedestrian traffic, offering views across the water to the industrial surroundings on both banks. Best visited during daylight when the structure and landscape are most visible.
The structure once had a bascule mechanism that could lift to let ships pass through the river. This lifting system operated until the late 1960s and reflects a time when the waterway served heavier shipping traffic.
