Situated adjacent to the Oak Street Connector, the architects designed a structure that has a scale compatible with the highway—a major change in scale for architects at that time. The corner stairtowers are reinforced concrete and provide the major structural support for the building. The steel beams spanning between the towers carry the floor loads but not the structure of the building, thus the steel did not have to be fireproofed and exists in the building in its truest form. The Knights of Columbus tower forms an entryway to the city and gives definition to the skyline. (New Haven Modern website)
