These retired traffic boxes are paid for by the City and installed on Boone County Property. Each year, the City invites local artists to apply for a public art project aimed at transforming these traffic signal boxes into works of art in the downtown area.

The project's goal is to reduce graffiti on these surfaces by turning them into appealing art objects. Once artists have decorated the traffic signal boxes, they become resistant to graffiti and vandalism, significantly enhancing the vitality and attractiveness of the streetscape. These boxes are retired due to maintenance needs, and when new equipment must be installed by the Public Works Department.
