This is a bridge for boats and it helps to connect the former east Germany to western Germany. It is almost a kilometer long and cost a billion dollars to build. There are many people looking at the bridge in the picture because this was the opening day for the bridge. Canals are often used in Europe because boats are an economical way to move heavy things if the boats do not go too fast.
A question for you. When a very heavy boat goes over this bridge is there more weight on the bridge? If there are several heavy boats on the bridge is there more weight on the bridge?
