What is the lifespan of a bridge?

Answer 1

it depends on what sort of bridge your researching for, for example a stone or a metal bridge will last up to 200 years, a metal bridge can last up to 500 years with modern rust.

Answer 2

Just like a bridge over a river or railway line , the answer depends on many factors.

The stress or amount of traffic on the bridge will be of prime importance.

Likewise the longevity of a dental bridge will depend on which teeth are bridged, the condition of the supporting teeth, the health of the gums and associated structures.The dietary habits of the wearer etc. And just as importantly, the material used in fabrication of the bridge.

So you see it's not like you can say " a bridge will last such a number of years"

The answer simply would be "It depends"
