Ciudad del Este's air quality reflects its position in the Paraná River valley at the Paraguay-Brazil-Argentina triple frontier, with the enormous commercial and smuggling trade generating extraordinary vehicle traffic on the Avenida San Blas and the Friendship Bridge corridor. The Itaipú dam reservoir to the north provides some humidity and limited ventilation, while the flat Alto Paraná terrain generally allows reasonable dispersal of the concentrated commercial district emissions.
