In the heart of Santiago is located the Plaza de Armas, the city's main square. With over 5 million people traffic congestion is a major concern for Santiagenos. However, the problem of traffic congestion around the Plaza de Armas was easily solved by turning some streets into pedestrian only boulevards - such as Ahumada, Huerfanos and Estado Streets. It is indicated that these streets are "indisputably busiest social, commercial and financial axis of Santiago."
With some clever street design, Santiago has managed to merge pedestrians and vehicular traffic creating an urban sinergy unique to Santiago's urban culture.
