What design choice did Eads make for the "Father of Waters" bridge?

The design choice for the "Father of Waters" bridge, completed by James B. Eads, to incorporate prefabricated modules was significant for several reasons. This approach allowed for efficient construction, as sections of the bridge could be manufactured in a controlled environment and then transported to the site for assembly. This method was particularly innovative for its time, leading to reduced construction time and improved structural integrity. The use of prefabricated components also facilitated repairs and modifications in the future, showcasing forward-thinking in engineering practices.

In the context of the other options, building entirely on-site would have been less efficient, resulting in longer construction times and potentially exposing the project to inconsistent weather conditions. The choice to use temporary materials would not align with the longevity and durability that Eads aimed to achieve with the bridge. Finally, avoiding steel would contradict Eads' groundbreaking use of steel in bridge design, which was a revolutionary shift during that era. Thus, the focus on prefabricated modules exemplified both innovation and practicality in Eads' design philosophy.
