The given pictures illustrate three different bridge designs.
Overview, it is clear that they are built depending on the water body for different transportation purposes. Thus the largest structure can be seen in the suspension bridge, while the opposite is true for the arch’s architecture.
In detail, arch bridge is constructed with the maximum length and height at 200 and 100 meters respectively, resulting in the smallest and shortest bridge, which just allows small boats to cross with the appearance as a semi circular without piers. In the case of deeper water like a river, concrete bridge is more fitting. Concluding a limited stretch at 300 meters, triple that of the arch one, this construction is at an ideal height for medium-size ships and other vehicles. Furthermore, it consists of the series of piers that will determine the curtail length of the bridge.
As for the remaining bridge, suspension lends itself to a vast and immense sea. Regarding its structures, there are two big piers placed on each side ranging from 400 to 2000 meters and anchored to the bridge by the number of suspender cables. This largest design is suitable to serve large size transports.
