1. The Beam Bridge
The beam bridge is one of the most commonly used bridges along with
arch bridges and is most effective over short
distances. They are very common due to the fact
they’re cheap and easy to build and they are very
strong over short distances as opposed to other
types. However the drawbacks of this type of
bridge are that they’re weak over long distances
and are not as pleasing the eye as some other
bridges such as Arch or Suspension.Beam
bridges can be made out of basically any
material.
The Cantilever Bridge
The Cantilever bridge is basically a variation of a beam bridge. The
roadway of the bridge is held in place by cantilevers, which are longpieces
going out into the water, but which are only anchored at one end. The
positives of a Cantilever Bridge is
that its able to carry large amounts
of weight and the span can be
greater thanthat of a simple beam,
because a beam can be added to the
cantilever arms.However the
construction of this bridge can be
challenging and expensive.
The Cable-Stayed Bridge
The cable-stayed bridge is a type of suspension bridge using its cables to keep it
up. Even this bridge is very similar to the suspension bridge its a lot cheaper. Along
with this there are a lot of other positives including the fact this bridge is
aesthetically pleasing and very modern looking, strong temperatures don’t affect
the cables in any way and the bridge has a low center of gravity which makes it less
venerable to earthquakes. There are negatives though, which includes the constant
maintenance needs of the cables and the bridge is easily affected by the wind.
