What was a key architectural feature of the bridge designed by Eads?

The design of the bridge by Eads is notable for its innovative use of material and construction techniques, particularly the incorporation of prefabricated modules. This approach allowed for more efficient assembly and greater structural integrity. The prefabricated elements made it possible to construct the bridge swiftly and with precision, which was a significant advancement in engineering at the time. Additionally, this method contributed to the overall strength of the bridge, allowing it to span large distances and support significant loads. In contrast, while cantilevers and classical columns are features seen in various bridge designs, they do not specifically represent Eads' unique approach or innovations. A completely stone-built bridge would not reflect the technological progress made by Eads, who utilized iron and steel to achieve his architectural vision.
