Which term represents the portion of a bridge above the bearings?

• A. Superstructure
• B. Substructure
• C. Bearings
• D. Deck

Answer: (A)

The part of a bridge that sits above the bearings is the superstructure. In bridge terms, the superstructure includes all components that carry the loads and span between supports—girders or trusses, the deck, and other load‑carrying elements. The deck is the road surface, but it is just one element within the overall superstructure. The substructure, on the other hand, lies below the bearings and includes foundations, piers, and abutments that transfer loads to the ground. Bearings themselves are the interface between the superstructure and substructure, allowing for movement and load transfer. So, the portion above the bearings is the entire superstructure.
