What is a "girder bridge"?

A girder bridge is a type of bridge that uses horizontal beams, known as girders, to support the deck and distribute the weight of traffic. Girders are typically made of steel or concrete and are placed at regular intervals beneath the bridge deck. This design allows for the efficient support of heavy loads while spanning longer distances. Girder bridges are commonly used for highways, railways, and pedestrian paths, providing a strong and stable structure. Their straightforward design makes them cost-effective and easy to construct, making them a popular choice for various bridge applications.
