Bridge

Why Are Bridges Built?

A bridge is a structure built to cross rivers without closing the way underneath.
Bridges aren't just used for racing tracks and bungee jumping.
They are used for safe transport across rivers and lakes making this faster and easier.
Before the 18th century when bridges were not invented people took punts to cross rivers.
This was a serious risk. People would drown in the process of crossing
which made this a serious problem.

In the 18th century bridges were not invented and people were not aware
of the consequences of crossing rivers.
The fastest way to get from point A to point B was to swim across.
Punts and boats were the most common choices to cross, but even so this
caused accidents and death.
The punts and boats that were commonly used were not as safe as you would think.
This sometimes caused the boats or punt to sink or break down.
It was soon obvious that they needed to invent a structure easier for people to cross from
point a to b.

Ever since bridges were commonly used transportation was safer, faster and easier for
people to cross.
Also instead of risking lives people soon noticed that more bridges should be made.
People then started requesting for more bridges because of the benefits of it.
This meant no danger risks, death and drowning. More bridges such as the beam bridge,
arch bridge and truss bridge were soon to be made.

Bridges are usually put in a gap or a valley.
The reason to this is because its a better way of transport. For example a valley.
Without a bridge you’ll need to drive down and back up to get to the other side.
All bridges are put on top of a gap rather than the bottom.
This allows us to get through from point a to b, which was a lot more faster than driving or
walking up and down
a valley.


Bridges are built for the purpose of safety, for cars to cross and a faster transport
from point a to b.  
Bridges today have saved us from what we commonly call the New Zealand disease.

This week for writing I have been focusing on an Explanation confirming why bridges
are made. During this process I used my researching skills to put in the correct amount of
information.
