An abutment in the context of construction refers to a supporting structure that is typically used to connect a bridge or viaduct to the ground or a retaining wall. Abutments are essential components of a bridge or similar structure, as they provide stability and resistance to the forces exerted on the structure, such as the weight of the bridge itself and the traffic passing over it. Abutments are usually made of concrete or steel, and are designed to distribute the load of the bridge evenly to the ground below.Abutments can come in various shapes and sizes, depending on the specific requirements of the bridge or structure they are supporting. They are often designed to withstand heavy loads and extreme weather conditions, and are built to last for many years
