They are supported by pillars are column's.
bridge supports are simply called support poles.
Bridges are classified by 3 criteria: material, structure, and construction method. Materials include steel, reinforced concrete, and stone. Bridge structures often seen range from cable suspension bridges to simple arch bridges. Bridges built with the cantilever effect are usually suspension bridges, and are supported only on one side until completion, whereas bridges built via the incremental launch method are built pieces at a time, with regular supports to the ground at each segment.
In simple terms, cable stayed use less cables then a suspension bridge. They are a combination of both beam and suspension. Suspension bridges hold the "deck" (where vehicles cross), via the cables, hence the term "suspension"; whereas, a cable stayed has the deck connected via the cables to anchorage points.
arch bridges can support more weight than beam bridges but for price i say beam won.
Bridges get their name by the kind of bridge they are

Suspension bridges are held, or suspended, from cables above the roadway's surface. This contrasts with bridges whose roadways are supported from underneath.
Bridges don't really know what OS you're using,only what network protocols are used.It's easy to find bridges that work on linux.The trouble is in finding bridges that are well supported in linux.
They can span difficult obstacles like water unlike supported bridges.
Suspension bridges are built to make use of tension, whereas most other types of bridges make use of compression to bear their load. Suspension bridges are usually designed with the deck suspended below a series of towers by cables. Other types of bridges are generally either designed with the deck being supported from below by pillars, or made up of an arch.

The full weight load is supported by vertical pillars, which makes them very strong.
Sydney's Harbour Bridge is supported by its huge steel arch. It is the tallest steel arch bridge in the world. Until recently it was the widest open span bridges. It was built in 1932.
Many bridges are NOT supported by a roller - however of those that NEED this type of design, if both ends were fixed solid - then as the bridge expanded and contracted with temperature, it would be forced to buckle in heat - or suffer extreme stresses when cooling - possibly to the point of structural failure and/or uprooting of the foundations of one or both sides.
Most highway bridges and railroad bridges are simple beam bridges. In this type of construction, the road surface or deck is supported by a series of longitudinal beams made of concrete, steel or timber. These in turn rest on bearings, which reston piers or abutments.
