From the beginning, businesses have adopted the Gateway Arch as a symbol of St. Louis. The Missouri Secretary of State’s online database of corporations lists more than six hundred corporations, present and past, whose name starts with the word Arch. 
Compared to the number of corporations starting with the word Gateway, that’s a handful. As I wrote in The Making of an Icon: The Dreamers, The Schemers, and the Hard Hats Who Built the Gateway Arch, the database lists four thousand of those corporations, present and past. It shows a mix of civic pride, acknowledgment that the Arch has made locals
realize how much St. Louis is the Gateway City, and a hope that the monument’s success will rub off on their own business.
