"deck bridge"的定义和意义

What is a "deck bridge"?

A deck bridge is a type of bridge where the roadway or deck is placed on top of the supporting structure, allowing vehicles and pedestrians to travel directly over it. The supporting elements, such as beams or trusses, are located below the deck, providing stability and strength. Deck bridges can be made from various materials, including steel, concrete, or wood, and are commonly used for roadways and railways. This design allows for efficient use of space beneath the bridge, making it suitable for areas where clear passage is needed for boats, vehicles, or pedestrians.
