A permanent fixture of Johnson Cityâs sesquicentennial celebration is nearing completion. Public Works Director Phil Pindzola expects construction on the history circle in King Commons Park, which is part of the larger legacy project, will likely wrap up next week. The project was concealed under a tent on Thursday, where crews were installing the elements that will ultimately make up the circle. Once complete, the history circle will consist of a series of concentric rings featuring blocks engraved with key dates and information about Johnson Cityâs history. A trio of tall passion flowers with bright filaments currently sit in the center of the circle.
