At City Hall on the corner of Front and Adams, hiding a huge HVAC unit (or whatever, some large piece of industrial equipment that looks bad on that corner) are a series of large panels made out of pieces of old street signs. The designs are intricate, colorful geometric patterns and resemble quilts from a distance. Since the material is reflective, I'm sure these look even more interesting at night. I searched around and could not find any information about the artist(s) or how this came to be, so if anyone has more information please let me know.
The whimsical and cheery artwork at the corner of Main and Jefferson is part of the Kids Color Downtown program sponsored by the Center City Commission and Memphis City Schools. It's purpose is to display student's artwork on some otherwise unsightly construction fences around Downtown. The art on this corner was created by Downtown Elementary School students.
