Demolition crews are beginning the first stages of the demolition of the old Knoxville Junior High and High School. Crews from DeCarlo Demolition began removing the corner stone on Tuesday. It is currently exposed. Work on removing the “Knoxville High School” sign on the north side of the building will begin first thing Wednesday morning. Before full demolition can begin, the building must have a perimeter fence placed around it, and they must separate the building from the administration offices on the south side.
