Steel Cable-Stayed Bridge

Although expensive, stayed bridges may be the only viable alternative when: there is no access to the gap, on which temporary or permanent piers could be built; when there is no staright level run up to the gap which would permit cantilever launching; when the span is too big for regular through truss bridges. And, in particular, one-tower bridges are useful if there is no good access to the far bank, as they can be built from one side only. But please note: you stll need enough space for the large counterweights, which may need to be one fifth of the spann for a two tower bridge.

• Long span (50m - 200m)
• Very strong, but also flexible
• Economical as allow a slender and lighter structure which is still able to span large distances
• Light weight is an advantage in earthquake-prone areas
• Modern and simple design makes attractive and distinct landmarks
• Easy to build in segments where in-situ construction or cantilever launch on rollers is not possible. This requires substantial piers and large counterweights
• Less suitable for very windy places due to its lightness
