In 1958 Morse Bros. built its structural prestressing plant in a nearby field in Harrisburg to supply prestressed girders for new highway construction throughout Oregon and the Northwest. The precast and prestressed industry throughout the United States organized and began developing design, manufacturing and quality standards that are still today the foundation of all precast/prestressed concrete. This organization is the Precast/Prestressed Concrete Institute (PCI).
