This just appeared a week or so ago on Carroll Creek bridge near Market St. Gorgeous, isn't it! It's a clock and is installed on both sides of the bridge. Kara Norman from Downtown Frederick Partnership says: "The sculpture was planned as a part of the original design of this pedestrian bridge. If you looked closely prior to installation of the artwork,there was a “missing” stone to allow for attachment. The first version of the artwork was not accepted by HPC. The City DED waited a year and re-applied to HPC and received approval. Ironmasters – the firm that made the iron bridge by the Delaplaine as well – created the artwork.
