Bridges and walkways

Bridges are structures that different civilizations have been building over time to overcome the different natural accidents with which they have encountered and thus be able to move their merchandise, allow the movement of people and move substances from one place to another. .

Depending on what transits from one place to another through them, they receive particular names, such as aqueducts, when they are used for water conduction, viaducts, if they support the passage of roads and railways, and walkways, they are destined exclusively for circulation of people.

Based on the materials with which they have been built throughout history, they are structured in bridges:

Made of wood. The first bridges are simply one or several trunks joining two banks of a stream.

Made of stone. The technological conquest of the arch allows to build stone bridges.

Made of iron. The industrial revolution brings the first bridges of this material.

Made of Concrete and steel. Current bridges are built by mixing these two materials.

It is in these last periods when metallic structures such as MS, are immersed in these constructions, dedicating themselves in almost all of them to the construction of the bridge board.
