Respecto del proceso de apertura de pasajes peatonales ejecutados por la comuna de Providencia a partir de 1970, se expone y evalúa la propuesta inicial versus su desarrollo durante los últimos treinta años, al tiempo que se examinan los cambios normativos que la operación ha desencadenado. Destaca la continuidad del proceso en el tiempo, que ha podido adaptarse a los cambios políticos y a los no menos importantes vaivenes económicos del país. Un conjunto de factores parecen haber hecho posible este proceso: un equipo técnico municipal visionario y  pragmático con respaldo político de la autoridad, implementando una gestión urbana que ha aunado constancia para la  persecución de los objetivos fundamentales y flexibilidad para la adaptación de la normativa y de los lugares de intervención planificados originalmente.AbstractThe author of this article analyzes and evaluates the original project of the pedestrian side streets by the Municipality of Providencia and the development of said project from 1970 and the following 30 years, also the normative changes caused by the completion of the project are examined here.
