Bridges diagram – Sample

The provided images compare 3 types of bridges.

First of all, the arch bridge, as the name suggests, has a curved shape. The total length of an arch bridge usually cannot exceed 200 metersand the Cao is 100 meters at maximum. It is mostly constructed on lakes, so only small size boats can travel below.

Next, the concrete girder bridge consists of a straight road placed on many piers that are constructed on the riverbed to support the bridge. It can be extended without limit based on the number of piers which can be upload 300 meters high and 200 meters apart. Therefore, ships at medium size can travel under the bridge.

Finally, the suspension bridge can be built across a sea channel. It can’t be between 400 and 2000 meters long, and the depth underneath is unlimited. It is supported by 2 towering Piers and a system of suspension cables. This kind of bridge allows the navigation of massive ships.

Generally, the 3 types of bridges are completely different in terms of length, depth, location, and waterway transport underneath them. (183)
