4. Architect Cass Gilbert Also Helped with the Bayonne Bridge

Architect Cass Gilbert, who designed the Woolworth Building, the United States Supreme Court in Washington D.C., and the U.S. Customs House at Bowling Green, also worked on the Bayonne Bridge with Ammann. The Bayonne Bridge had two different designs before the spandrel arch type of bridge was decided on: a conventional suspension and a cantilever. The arch was the only solution that could accommodate the rail transit tracks required at the time.
