City of Vicksburg Street Department employees, from left, Harold Miller, Cory Davis and Donald Graves break up concrete in front of the former Thomas Furniture Store at 713 Clay St. Wednesday morning. Foreman Donald Graves said the concrete had aged and cracked and needs to be replaced and that his team should be finished Monday. Acting city engineer Garnet Van Norman said the sidewalk was damaged in 2006 when a building collapsed and again, during the partial clearing of the debris.
