A box girder bridge is a type of bridge with a rectangular or box-like cross-sectional shape. This design provides structural strength and stability, making it suitable for medium to long-span bridges. The enclosed structure of the girder helps distribute loads effectively and can be made from various materials, such as concrete or steel. Box girder bridges are known for their reduced maintenance needs, versatility, and aesthetic appeal. They are commonly used in highway, railway, and pedestrian bridge construction
