The design and equipment necessary in precast concrete operations has progressed in recent years to such an extent that the resulting products are now being used satisfactorily in many types of construction. This report covers two precast concrete products which the Department of Highways authorized in contracts let in 1954 and 1955. These items however, are not the first precast concrete products to be used by the Department. Two concrete bridges are known to have been precast and placed in Scott and Graves County sometime ago. Precast concrete cribbing has also been used for quite some time.
