During the 1960s and 1970s, Denver was one of the epicenters of the Chicano Movement. The boxer-turned-activist Rodolfo "Corky" Gonzales formed an organization called the Crusade for Justice, which battled police brutality, fought for bilingual education, and, most notably, hosted the First National Chicano Youth Liberation Conference in March 1969.
State Highway 470 (C-470, SH 470) is the southwestern portion of the Denver metro area's beltway. Originally planned as Interstate 470 in the 1960s, the beltway project was attacked on environmental impact grounds and the interstate beltway was never built. The portion of "Interstate 470" built as a state highway is the present-day SH 470, which is a freeway for its entire length.
