What is the history of Chicano park?

In 1970, the construction of a highway patrol station in the area galvanized Chicano activists and Barrio Logan residents: They protested, demanding a space of their own, free from development. The resulting land, located under the bridge, became known as Chicano Park.

Chicano Park, in San Diego, California, was the site of a powerful protest in 1970 by members of the local San Diego Hispanic community over the planned redevelopment of a vacant site within the Barrio Logan community that had been previously promised to the community as public open space.

Explanation:

The artist Salvador Torres proposed to transform the bridge's massive concrete pylons into a towering canvas for expression in the spirit of the Mexican Mural Movement. The formation of Chicano Park was signed into law in 1971 and mural painting began two years later.
