This type of bridge is made up of multiple connected sections. These sections work together to help distribute the forces throughout the entire bridge, so that it can cross great distances and support a large amount of weight. The size of the components in each section is small,which makes this type of bridge ideal for places when long sections cannot be shipped or where large cranes and heavy equipment cannnot be used during construction. However,a bridge of this type of this type encloses the space above the roadway,possibly distracting driver's attention.
