Which option describes a decorative concrete railing used for architectural effect on bridges?

• A. Concrete Balustrade
• B. Concrete Parapets
• C. Precast Concrete Railings
• D. Concrete Bridge Railing

Answer: (A)

Concrete balustrade is the decorative railing style used to achieve architectural effect on bridges. It features a row of balusters supporting a top rail, allowing ornamental detailing while still providing safety at the edge of the bridge. Parapets are typically solid barriers focused on protection rather than ornament, and precast concrete railings are modular sections that may be functional or decorative but don’t inherently denote architectural embellishment. A general concrete bridge railing is a broad term that could be either plain or decorative, so it doesn’t specify the decorative character. Therefore, the decorative option is concrete balustrade.
