As San Francisco’s Golden Gate Bridge celebrates its 85th birthday, New Jersey celebrates the company that made the steel wire.

A building in Trenton was home to John Roebling’s company in the 1900s.

For decades, this company made steel ropes for some of the nation’s biggest and most ambitious construction projects.

The creation of this bridge that would become an American icon would not have been possible without the company on Hamilton and Clark Street in downtown Trenton.
