Located in “La Boca” neighbourhood, from becomes Boca Juniors (the most popular Argentinean football team), people from the city use to name this extraneous metallic structure as “the old brigde”. I think this is not precisely a bridge. Hide on the right side of the structure, there is a platform that hangs up from a huge metallic arm. In the top of this arm there are wheels that allows it to take the plaftorm from one side of the river to the opposite. Nobody could explain me why the structure should had such a height. It could be long time ago huge ships used to sail this river.
