It takes time and a lot of money to construct a suspension bridge. Initially, bridges were constructed primarily to connect one place with another, and to offer passageways over obstacles like a body of water. Such bridges must be strong enough to provide the best service to passengers and drivers. Strong bridges can not only avoid collapse, but also offer regular transportation flow.
For some time now, many governments around the world have spent millions and billions of dollars to construct durable bridges, and are often monitoring and maintaining them to make sure they are in good condition. Here are the most expensive bridges of all time.
