The correct response highlights that decking is not considered a basic part of a bridge structure, particularly when compared to other essential components.

A bridge is fundamentally composed of several crucial structural elements that ensure its integrity and functionality. Piers provide vertical support for the bridge deck and transfer loads down to the foundation. Abutments serve to anchor the ends of the bridge and bear the lateral loads from the bridge structure itself. The roadway, which is the surface on which vehicles travel, is typically included within the overall bridge structure.

While decking is important, it refers specifically to the surface material of the roadway and is often viewed as an element rather than a foundational component of the entire bridge structure. This distinction clarifies why decking may not be categorized alongside piers, abutments, and the roadway as a basic part of a bridge's overarching structure.
