Gran Avenida

Gran Avenida is a major north-south axis, 21 kilometers in length, that crosses five communes of the Greater Santiago metropolitan area. The corridor begins at Alameda Libertador Bernardo O’Higgins (the city’s historical center) as a one-way pair of streets, Nataniel Cox and San Diego, which merge at the Zanjón de la Aguada creek to form Gran Avenida. Gran Avenida continues south to the La Cisterna commune, where Los Morros Avenue splits off to the east. The western continuation of Gran Avenida enters the center of the San Bernardo commune, where it runs parallel to a north-south intercity rail line before changing names to Avenida Portales and finally merging with the Panamerican Highway, which continues to the south of Chile.

As an axis of the city’s growth, Gran Avenida exemplifies Santiago’s traditional pattern of urban segregation, with middle and high income residents near the historic center and groups of lower income residents concentrated in dense peripheral areas. Addressing this segregation, and the associated lack of services and opportunities in the outlying areas, is a key planning and transportation challenge. At the same time, through its role as a metropolitan connector, important amenities and government facilities are located along the avenue, including forty-three educational institutions, three regional shopping centers, two major hospitals, and a military base.
