1 The Construction of a Suspension Bridge There are six main processes when it comes to the construction of a suspension bridge. Firstly the anchors that are going to support the cables need to be set into the ground. They are normally made from concrete and need to be set into solid ground as these support a big proportion of the deck. The next part of the process is to construct the foundations for the towers. If the towers are to be constructed in water then the water needs to be dammed and pumped out. This is not the only problem though as wherever the towers are going to be the foundations need to be on solid ground as it is the towers that are under compression and transfer the applied loads into the ground as the diagram shows above. The third stage to the construction process is to erect the towers. This is a key stage as suspension bridges are renowned for spanning long distances and the higher the towers are the longer the bridge will be able to span. Next the main cable needs to be stretched between the two anchor points and over the two towers. At the top of the two towers sit two saddles. These are joints that the cable can run freely over and they allow for any slight movement in the bridge. If this movement was not
