This bridge is an extremely rare and significant example of a Abt Bascule bridge, also sometimes referred to as an American Bridge bascule. The design was invented and patented by Hugo A. F. Abt who worked for the American Bridge Company. View The Original American Patent For The Abt Type Bascule Bridge Or View The Canadian Patent. The name Abt bascule comes from Hugo Abt's name, although some sources also turn Abt into an acronym, American Bridge Type, ABT. It is an extremely unusual and fascinating type of trunnion bascule bridge. The design is described in detail by Hugo A.F. Abt in 1921 in his original patent, which are on file in both the United States and Canada. The Port Huron Railroad Bridge appears to very closely follow the patented design, and it contains all the essential details claimed in the patent. There appear to have only been eight Abt bascule bridges ever built, and today only six remain nationwide including Port Huron's bridge. Little has been found about the details of Hugo A. F. Abt's life. He did hold a couple additional bascule bridge patents. View A Second Bascule Design Patent By Hugo Abt and a Third Bascule Design Patent.
