The pictures illustrate the differences between types of bridges. Overall, these bridges are constructed to serve various locations such as seas, lakes and rivers. Additionally, there are differences in the structure and height of each bridge.
The arch bridge is built above a lake, with a height of no more than 100 meters and a width of no more than 200 meters, making it suitable for small ships. Its structure is quite simple, with an arched shape. In contrast, the structure of the concrete girder bridge is more complex. It is built over a river, which allows medium-sized ships to sail. The distance from the riverbed to the bridge is 300 meters. This bridge has five piers, which are placed no more than 200 meters apart. There is no limit to the span of the bridge as it depends on the number of piers.
Finally, the suspension bridge is constructed between two banks of the sea, where large ships often pass. Unlike concrete girder bridges, this bridge only has two piers, which are built at a close distance to the banks with the middle being very deep. The span of this bridge is from 400 to 2000 meters, depending on the topography.
