In Mexico City, some people spent up to 6 hours a day in their car, going to and from their work place. Travelling over the totality of the Anillo Periférico (the freeway that surrounds the entire the city) may take between 5 and 7 hours. Imagine millions of drivers carrying out this journey very slowly, fighting boredom by contemplating the cityscape. Mi proposal consists in a series of interventions on the pedestrian bridges that punctuate this circuit. Each bridge would have an epigram or an aphorism from authors presented in chronological order. This peripathetic scheme would show a selection -obviously a partial one- of universal thought, which could nevertheless be a threshold toward a deeper interest.
