IELTS Essay Task 1: Bridges

The diagram details 3 different constructions for bridges. Looking from an overall perspective, it is readily apparent that concrete girder bridges are potentially the longest and tallest, while suspension bridges allow for the largest ships to pass underneath. Arch bridges are not as tall or long and admit only the smallest ships.
Looking first of all at arch bridges, the permissible height is no more than 100 meters and the length is typically under 200m. These bridges are built over lakes, have a conical shape, and cover the smallest ships.
In contrast, concrete girder bridges can be an indeterminate length, though the maximum height is 300m. Concrete bridges are built over rivers and require a series of piers spaced under 200m apart to provide support, only allowing for the passage of medium-sized ships.
The modern suspension bridge can be between 400 and 2000m long and it is possible to build it over very deep seas as long as there is shallow land for pier structures to link at either end. The distance between piers enables the largest ships to traverse below safely.

This picture portrays details of 3 different bridges, an arch bridge, a concrete girder bridge, and a suspension bridge. From an overall perspective it is readily apparent that each of these bridges are built over contrasting water bodies and are of various strengths, heights as well as lengths.
Firstly, the arch bridge, suitable over a lake is not more than 100m in height and not more than 200m in length, allowing only small ships to pass under. Whereas the concrete bridge placed over a bigger water body, a river, is maximum 300m in height being the reason middle sized ships can sail under. Moreover, the distance leads to an unlimited extent which depends on the number of piers that contain an utmost breadth of 200m between them.
Lastly, the strongest bridge of the three, the suspension bridge, is built over the largest water body, the sea. The distance between each pier of the bridge lays in between 400m to 2000m. Meanwhile, large size ships cross under the bridge detailing that the height is much greater than that of the arch and concrete girder bridge.
