What is single-span bridge?

A single-span bridge is a type of bridge that consists of only one span, or section, between two supports. This type of bridge is typically used for short to medium-length spans and can be made of a variety of materials, including steel, concrete, or wood.

Single-span bridges offer a number of advantages over other types of bridges. They are often simpler and less expensive to construct than multi-span bridges, and they can be erected more quickly. Single-span bridges are also more flexible and can be designed to accommodate a wider range of traffic loads and environmental conditions.

However, single-span bridges also have some disadvantages. They are not suitable for very long spans, and they may require additional support structures or piers if they are located in areas with high winds or heavy traffic. Additionally, single-span bridges may need to be reinforced or replaced more frequently than other types of bridges, depending on the materials used in their construction and the conditions they are exposed to.
