CLSI is proud to have been the lead civil engineer for the Union Bridge and New Windsor quarry operations of Lehigh Hanson of Heidelberg Cement Group. Most recently, beginning in 2007, CLSI began working on the conceptual layout of a 4.5 mile overland belt conveyor. The conveyor connects the New Windsor Quarry and the Union Bridge plant for limestone transportation. After reviewing multiple options, the belt conveyor proved to be the best and most community friendly option.
