A.BRIDGES_NOTES

=BRIDGES=

=== Some questions to reflect about: ===  ====**1. Are all bridges alike?** ==== Think of the bridges you remember:
 * What are they made of?
 * The bridges I remember are made of wood, iron, stone, brick, concrete, aluminium.

 ====**2. What social and/or political benefits can bridges provide to places?** ====
 * What are they connecting?
 * these bridges connect cities, sections of places, etc.
 * How is the span between their piers or towers?
 * normally is long and wide, people and even cars can go through it.
 * Why were the bridges built?
 * Bridges are and have been useful for civilizations because of its property and specific function of " connecting ". This connection implies less time for traveling or move from a place to another, from the field to the cities, it gave people the opportunity to live somewhere and work in the other side of the bridge, unlike in the past when this was not possible. It also gave people the opportunity to travel for leisure to new places that before were not physically accessible.
 * Did they provide benefits? To whom? Why?
 * Among history, bridges have been useful during wars and for clans to get new lands and conquer new empires, this made several civilizations grow and expand without many physical barriers, also for the same civilizations to run away from climate changes and move from a hostile place to a better one. Nowadays, it is usually necessary for the transportation of products from a city to another and for the mobility of the people.
