• A. Undivided Carriageway
• B. Cast-in-Place Concrete Deck
• C. Divided Carriageway
• D. Timber Deck

Answer: (C)

Divided carriageway refers to a bridge deck arrangement where lanes for traffic in opposite directions are separated by a median or barrier, creating two distinct carriageways. This separation improves safety by preventing head-on conflicts and helps manage traffic flow on the deck. It’s not about the deck’s material or how it’s constructed: a cast-in-place concrete deck describes construction method, and a timber deck describes the material used. It’s also not an undivided carriageway, which lacks any physical separation between opposing directions. So the described deck matches the concept of a divided carriageway.
