The League of American Bicyclists has rated Colorado as the sixth most bicycle-friendly state in the nation for the year 2014. This is due in large part to Front Range cities like Boulder, Fort Collins and Denver placing an emphasis on legislation, programs and infrastructure developments that promote cycling as a mode of transportation. Walk score has rated Denver as the third most bicycle-friendly large city in the United States. According to data from the 2011 American Community Survey, Denver ranks 6th among US cities with populations over 400,000 in terms of the percentage of workers who commute by bicycle at 2.2% of commuters. B-Cycle – Denver's citywide bicycle sharing program – was the largest in the United States at the time of its launch, boasting 400 bicycles. Through the acquisition of new grants, the program has expanded each year, adding dozens of new stations, hundreds of bikes, and by beginning service during the winter months.
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.
