A simple suspension bridge (also rope bridge, swing bridge (in New Zealand), suspended bridge, hanging bridge and catenary bridge) is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end. They have no towers or piers.

A bridge can be categorized by what it is designed to carry, such as trains, pedestrian or road traffic (road bridge), a pipeline (Pipe bridge) or waterway for water transport or barge traffic. An aqueduct is a bridge that carries water, resembling a viaduct, which is a bridge that connects points of equal height.
Footbridges can also be built in the same ways as road or rail bridges; particularly suspension bridges and beam bridges. Some former road bridges have had their traffic diverted to alternative crossings and have become pedestrian bridges; examples in the UK include The Iron Bridge at Ironbridge , Shropshire , the Old Bridge at Pontypridd and ...
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
As long as the tree from which it is formed remains healthy, the roots in the bridge can naturally grow thick and strengthen. New roots can grow throughout the tree's life and must be pruned or manipulated to strengthen the bridge. Once mature, some bridges can have as many as 50 or more people crossing, and have a lifespan of several hundred ...
A girder bridge is a bridge that uses girders as the means of supporting its deck. [1] The two most common types of modern steel girder bridges are plate and box. [citation needed] The term "girder" is often used interchangeably with "beam" in reference to bridge design.
The simple design, ease of manufacture, and ease of construction of the Pratt and Howe trusses spurred Benjamin Henry Latrobe II, chief engineer of the Baltimore and Ohio Railroad, to build large numbers of iron bridges. After two famous iron bridge collapses (one in the United States, the other in the United Kingdom), few of these were built ...
