The Colfax Avenue Business Improvement District hosted the Art-i-fax Street Party on Saturday, where Denver Public Works opened up parts of Colfax and its side streets to people, so volunteers could add some color and creativity to two intersections.

These pieces are at Race and Williams, several blocks away from two new intersection murals on Steele and Adams streets in Colfax’s Bluebird District. Each piece is different, but they’re all funded with grant money from the city’s P.S. You Are Here program, “a citywide creative placemaking and neighborhood revitalization program that cultivates collaborative, community-driven, outdoor projects in Denver’s public spaces.”

These artworks are no substitute for physical street redesigns, but they can slow drivers down by creating “mental speed bumps.” The Colfax BID is working on other, bigger streetscape improvements — it’s developing a master plan, in fact — and wants the public to weigh in with this survey.
