Bayonne Bridge: The Work of Othmar Ammann, Master Builder

Abstract

The goal of this paper is to demonstrate the significance of the Bayonne Bridge and to identify it as a work of structural art, because its designer, Othmar Ammann (1879–1965), focused on efficiency, economy, and elegance. To understand Ammann’s ideas and his great arch bridge, we will: (1) briefly describe his educational background; (2) explore his design concept; (3) explain the behavior of the bridge through a careful structural analysis; (4) include a critical analysis of its design; and (5) reflect on lessons to be learned from Ammann. A full, modern technical study of the Bayonne Bridge has never been published. Since we are very fortunate to have one of the few complete sets of the plans, we will present an independent structural analysis to explain Ammann’s design concept and to demonstrate its efficiency in the complete form and its safety during construction.
