Precast Concrete Deck consists of panels precast off-site and transported to the bridge.

• A. Precast Concrete Deck
• B. Cast-in-Place (CIP) Concrete Deck
• C. Orthotropic Steel Deck
• D. Timber Deck

Answer: (A)

This describes a precast deck system, where panels are cast off-site in a controlled factory setting and then transported to the bridge for installation. That off-site fabrication and field assembly is the hallmark of a precast concrete deck, offering benefits like higher quality control, faster construction, and reduced on-site formwork and weather exposure. The other deck types don’t fit this description: a cast-in-place deck is poured directly at the bridge site, an orthotropic steel deck uses a steel deck with a concrete or composite topping rather than precast concrete panels, and a timber deck uses wood rather than concrete panels.
