What is an advantage and disasvantage of a suspension bridge?

Answer 1

PRO: they can be built over waterways, and can be built high, letting taller ships to pass under

PRO: Temporary supports in the middle to keep the bridge from falling aren't needed to keep the bridge from collapsing

CON: They are very flexible and can bend under heavy loads if they are in one spot

CON: They use expensive foundation work with all the load going on if in soft ground

Answer 2

Advantages: *

It can be built over water, it can also be built high which lets ships travel under. *

It is very flexible, which allows it to withstand earthquakes and powerful winds *

Disadvantages: * **

The flexibility is also a disadvantage because it can not take extreme heavy weights **

If they are built of soft ground it can increase the cost to build. **

got this for homework copyed it of my homework :) soz its long ++++ Built over water / can be built high. So are, and can, most bridges! The suspension bridge's main advantage is that it can be built over a very much longer span than any form of arch or beam (truss) bridge. The height is immaterial except in often necessitating long approach embankments and viaducts. Soft ground: the geology affects any bridge. The foundations are always taken down below the surface sediments to rest on solid rock. Flexibility: that itself does not affect the weight. Bridges of any type are designed to take a predicted weight of traffic. However that flexibility, although in fact very slight, is enough to make the suspension bridge unsuitable for railways.
