In the item-number list, which component uses number 59?

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

Answer: (B)

Item numbers in a bridge inspection reference are grouped by component, with each major part having its own number range. The numbers in the 50s are designated for the superstructure, which includes the load-carrying elements above the deck such as girders, trusses, bearings, and expansion joints. Since 59 falls within that superstructure range, it is used for a superstructure item. The deck, substructure, and culvert each have their own separate ranges, so they would not use the number 59.
