Bridges are the structures that help us to pass over the physical obstacles (such as body of water, a road or a valley) in or on the land/ earth.
The bridges are spanning structure built with the purpose of providing a passage over the various obstacles. There are various designs of the bridges and they all may serve different purposes.
The design, the type and the strength of a bridge varies depending upon a number of factors. Some of these factors include the use for which bridge is being built, the terrain where it is being anchored and the materials used etc.
Many of the strongest bridges in the world are credited to the strength because of the material used in the making and the design as well. The Rolling Bridge in London, opened in 2004 is a truss bridge and is considered the strongest bridge in the world.
Only bridges that are strong enough can be used for a long period and be sustained for a longer period.
The strength of the bridges is one of the important factors. The Henderson Waves is the second strongest bridge, is located in Singapore, opened in March 2008. The other strongest bridges of the world include the Sundial Bridge, the Millau Viaduct, the Python Bridge and many others.
