Not really a bridge, but bit more of an observation deck to view the majestic Iguazu waterfalls.
Iguazu Falls are waterfalls of the Iguazu River on the border of the Argentine province of Misiones and the Brazilian state of Paraná. Together, they make up the largest waterfall in the world. The falls divide the river into the upper and lower Iguazu. For most of its course, the river flows through Brazil; however, most of the falls are on the Argentine side.
