A bridge is a structure built to span a physical obstacle, such as a body of water, valley, or road, without closing the way underneath. It is constructed for the purpose of providing passage over the obstacle, usually something that can be detrimental to cross otherwise.

There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it.

In Nigeria, the Lagos Third Mainland Bridge is the longest of the three bridges connecting Lagos Island to the Mainland. It was the longest bridge in Africa until 1996 when the 6th October Bridge located in Cairo was completed. The bridge starts from Oworonshoki which is linked to the Apapa-Oshodi expressway and Lagos-Ibadan expressway, and ends at the Adeniji Adele Interchange on Lagos Island.
There are numerous publications, journals, articles and books on Bridge Construction. To learn more, kindly visit www.ascelibrary.org or www.asce.org/publications.
