The Knox County Sheriff's Office has received several reports of concrete items being thrown from Interstate and Highway overpasses. To help prevent death or great bodily harm the Sheriff's Office has deployed resources and conducted surveillance on overpasses in Knox County.

On February 26th, 2024, the Knox County Sheriff's Office was dispatched to the 1900 block of West Knox Road, the overpass of US Highway 34. A passerby complained of concrete being thrown from the bridge.
