You don't have to know anything about engineering or building to appreciate a structure like Argentina-Paraguay Bridge. Stand back and take in the craftsmanship and creativity on display.
You'll have sightseeing choices galore when in Posadas. Argentina-Paraguay Bridge is an ideal place to begin here, but there are numerous other worthwhile places to consider. San Jose Beach, 9 de Julio Plaza, and Parque Republica del Paraguay are not far from the modern structure and will fill in your day nicely.
