Sub Structure
They are supported by pillars are column's.
well, for my opinion, i think a suspension bridge why: because for of all the cables support the roadway and the two towers looking things at the bottom also supports while for the truss bridge it is only trusses. and if you building a bridge then it depends on what and how you use to build it. good luck!
chords (top and bottom) verticals (also called vertical members) diagonals (also called diagonal members) floor beams deck pinned support (also called a fixed bearing) roller support (also called an expansion bearing) abutments (or piers)
Tower Bridge
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
A support pole
Arches are among the oldest forms of structural support. Unlike beam bridges, arch bridges are curved. The arch carries the weight outward along the curve to the supports on each end of the bridge, called abutments. The abutments carry the load and stop the bottom of the bridge from spreading out.
the bottom chord is the bottom part of the bridge that holds everything in place.

A bridge with overhead cables to support it.

The Chinese bridge is called Kangshaun great bridge

London Bridge doesn't have any support cables.
the weight on top is equal to the resistance on the bottom of the bridge.
