Suspension/Cable-stayed - The deck
(trafficway) of a suspension bridge is
hung by cables which hang from
towers. The cables transfer the weight
to the towers, which transfer the
weight to the ground.
Cable-stayed bridges have towers, but
cables from the towers go directly to
the road deck, instead of spanning
from tower to tower.
Cantilever - In the cantilever
type of bridge, two beams
support another beam, which is
where the deck or trafficway is.
The two beams must be
anchored, and this must be
There are 2 to 3 support beams
depending on the wave tops they are
usually used where waters are deep.
A truss bridges is made of triangulation
mostly out of steel bars, they are frames
of a tunnel when looked at from the side
and front view.
A draw bridge is a bridge that opens at
the top to allow ships and boats to pass
under it as they are not high bridges..
Very similar to a suspension bridge but
instead of steel bars, it uses reinforced
