it is reported that the bridge was designed in such a way in order to slow traffic and allow drivers and pedestrians to “appreciate panoramic views to one of the most beautiful and pristine coastal landscapes in Uruguay.”. Pedestrian crosswalks allow pedestrian access to sidewalks on both the inner and outer edge of the circle.

But extra (kilo)meters for the pedestrians which use the bridge on regular basis.
Is it regularly used by pedestrian or is it more of an attraction?
