Bridges have been important since the first human walked the surface of the earth. The first bridges were primitive and natural. Rocks in an river and blown down threes are examples of these witch made the movement of humans a lot faster. What is really fascinating is how this natural bridges became large structures stretching tenths of kilometers.
In my in depth project I will try to find out how it is possible to build this fascinating structures, and maybe even try to describe one magnificent bridge.
