Due to repeated stress and strain, the material used in the bridges loses elastic strength and ultimately may be collapsed. Hence, bridges are declared unsafe after long use

Because of cracks and corrosion. Actually, poor maintenance is the cause of ALL modern bridge failures and closures.
Bridge demolition would be used to demolish a bridge due to it being unsafe or if it were to be replaced with a better built bridge. Often bridges become unsafe in which case it would have to be demolished and rebuilt.
DO NOT DO THIS!!! UNSAFE!!!!!!!!!! UNSAFE!!!!!!!!!!!! UNSAFE!!!!!!!!!!!!!!
They are suspension bridges. One of the well known examples is the Golden Gate Bridge in San Francisco.
because to give long span we use arch
Doing dangerous things will make you unsafe. Inspectors found unsafe conditions in the company's factory.
I use Plastruct for modelling bridges.
yes, most electric violins use normal bridges.
DO NOT USE UNTIL CHECKED OVER BY A COMPETENT GUNSMITH OR SEND IT BACK TO BROWNING!!!!!!!!!!! UNSAFE!!!!!!!!!!!!! UNSAFE!!!!!!!!!!!!!!!! UNSAFE!!!!!!!!!!!!!!!!
It can be safe and unsafe depending on how you use it.
Certainly some bridges can. Swing bridges, bridges that raise up, these though, stay in one location. Pontoon bridges are capable of being moved from place to place and are in use worldwide.
The longest bridges in the world are viaducts or trestle bridges. It is easier to design a high, elevated roadway by directly supporting it with many towers or piers (as in a viaduct or trestle bridges). It is more difficult to design an elevated roadway with a large unobstructed span (as in a suspension bridge or arch bridge). However, the bridges with the longest unobstructed spans in the world are invariably suspension bridges, because ...
