Which term describes a bridge that carries road traffic over a channel or valley?

Explanation:
A bridge is the structure built to span an obstacle and provide passage for road traffic. When you need to carry vehicles over a channel or valley, the overall term for that complete structure is a bridge, which includes the deck, girders, and substructure as its parts. The deck is the roadway surface, girders are the main horizontal supports, and the substructure (such as abutments and piers) transfers loads to the ground. Therefore, the whole thing used to cross the obstacle is a bridge.
