I just stumbled on this, but I needed to respond to say Trenton WAS known for making bridges. The John A. Roebling's Sons Company is most famous for making the Brooklyn Bridge, but also manufactured the steel wire used in bridges across the world, including the Golden Gate Bridge. This is the industry that inspired the motto on the Lower Trenton Bridge.I remember seeing the "Trenton makes..." sign on that bridge, and I wondered just what it was that Trenton was so known for making?
(I kind of hope it was bridges) ?
