A TYPICAL CABLE STAY BRIDGE | |

A scientific understanding of the properties of
modern materials and the availability of computer software have made it
possible to construct new types of bridges. A typical cable stay bridge
can be seen below. These are modern bridges designed using computer
aided design (CAD). Bridge designers are now able to design a bridge on
computer, simulate its use and correct any faults before building
begins. Modern materials, especially special steels are used to
construct this type of bridge. This means that bridges can be made from
lighter, stronger materials and engineered precisely. Today materials
are used efficiently. |

Unlike suspension bridges, cable stay bridges do not
need anchor blocks. The cables are fixed to either side of each tower -
this means that the weight of each side of the bridge counter balances
the opposite side. |

Two well known cable stay bridges can be found in France. The ‘Le Pont de Normandie’, can be found in Normandy, Northern France. This was once the longest cable stay bridge in the world. However, this engineering feat has been surpassed in dramatic style by the opening of the Millau Bridge in Southern France. This cable stay bridge is the highest bridge in the world, with its deck almost at the same height as the Eiffel Tower. |
