Activity sheet 1 – How well do you know your bridges?
Match the pictures with the descriptions below.
- It has a basic design and is the most affordable. Piers on either end support the horizontal beam. The weight rests on these piers. It is not very high, so ships are unable to pass under it.
- It is attractive and modern looking. It spans between 150–850 metres. It is built quite quickly and is cost effective. The bridge is supported by cables, which are all attached to towers and to the road at regular intervals in various patterns.
- It is the most expensive bridge to build, but it is the lightest and most attractive. The sides are anchored down and the cables help distribute the weight evenly. It spans between 600–2000 metres.
- It is the oldest type of bridge. It has excellent natural strength because weight is distributed along the curve of the arches. It spans between 60–250 metres.
Label the parts of the bridge that helped you to decide which type it was.
