A bridge deck or roadbed is the roadway, or the pedestrian walkway, surface of a bridge. It is not to be confused with any deck of a ship.
The deck may be of concrete, which in turn may be covered with asphalt concrete or other pavement. The concrete deck may be an integral part of the bridge structure (T-beam structure) or it may be supported with I-beams or steel girders (floor beams). The deck may also be of wood, or open steel grating.
