Supporting structures of the bridge are referred to as what?

In bridge terminology, the supporting structures are referred to as substructures. These elements are crucial as they provide the necessary support for the bridge, transferring the loads from the superstructure to the ground. The substructure typically includes components such as footings, piers, and abutments, which are designed to hold the weight of the bridge and maintain its stability against various forces, including traffic loads and environmental conditions.

The superstructure, on the other hand, is the part of the bridge that is above the substructure, including the deck and any supporting beams or trusses. While it plays a vital role in the bridge's functionality, it does not encompass the supporting elements that are specifically associated with the term "substructures."

Understanding this distinction is important for engineering and construction practices, as well as for assessing the overall integrity and design of bridge structures.
