The walls of the former Will County Courthouse came tumbling down as exterior demolition kicked off, with contractors targeting the building’s visage after concluding a two-month venture gutting its insides. The demolition began on Friday and is slated to run through March or April, the Chicago Tribune reported. A Carol Stream outfit, American Demolition Corporation, is at the helm, having secured a near $1.5 million payday last autumn for erasing the four-story structure from Joliet’s landscape.
