Outline of bridges

The following outline is provided as an overview of and topical guide to bridges:

Bridges – a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle.

What type of thing is a bridge?
Bridges can be described as all of the following:
 * A structure – An arrangement and organization of interrelated elements in a material object or system, or the object or system so organized.
 * A thoroughfare – A road connecting one location to another.

Types of bridges

 * Beam Bridge
 * Truss Bridge
 * Truss arch bridge
 * Cantilever Bridge
 * Stressed ribbon bridge
 * Arch Bridge
 * Tied Arch Bridge
 * Through arch bridge
 * Skew arch
 * Suspension Bridge
 * Cable-stayed bridge
 * Simple suspension bridge
 * Inca rope bridge
 * Tubular bridge
 * Extradosed bridge
 * Moveable Bridge
 * Drawbridge (British English definition) – the bridge deck is hinged on one end
 * Bascule bridge – a drawbridge hinged on pins with a counterweight to facilitate raising ; road or rail
 * Rolling bascule bridge – an unhinged drawbridge lifted by the rolling of a large gear segment along a horizontal rack
 * Folding bridge – a drawbridge with multiple sections that collapse together horizontally
 * Curling bridge – a drawbridge with transverse divisions between multiple sections that curl vertically
 * Fan Bridge - a drawbridge with longitudinal divisions between multiple bascule sections that rise to various angles of elevation, forming a fan arrangement.
 * Vertical-lift bridge – the bridge deck is lifted by counterweighted cables mounted on towers ; road or rail
 * Table bridge – a lift bridge with the lifting mechanism mounted underneath it
 * Retractable bridge (Thrust bridge) – the bridge deck is retracted to one side
 * Submersible bridge – also called a ducking bridge, the bridge deck is lowered into the water
 * Tilt bridge – the bridge deck, which is curved and pivoted at each end, is lifted at an angle
 * Swing bridge – the bridge deck rotates around a fixed point, usually at the centre, but may resemble a gate in its operation ; road or rail
 * Transporter bridge – a structure high above carries a suspended, ferry-like structure
 * Jet bridge – a passenger bridge to an airplane. One end is mobile with height, yaw, and tilt adjustments on the outboard end
 * Guthrie rolling bridge
 * Vlotbrug, a design of retractable floating bridge in the Netherlands
 * Locks are implicitly bridges as well allowing ship traffic to flow when open and at least foot traffic on top when closed
 * Rigid-frame bridge
 * Side-spar cable-stayed bridge
 * Segmental bridge

General bridges concepts

 * Bending The behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element.
 * Compression (physics) The application of balanced inward ("pushing") forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions.
 * Shear stress The component of stress coplanar with a material cross section.
 * Span (engineering) The distance between two intermediate supports for a structure.
 * Tension (physics) The pulling force transmitted axially by the means of a string, cable, chain, or similar one-dimensional continuous object, or by each end of a rod, truss member, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at each end of said elements.
 * Torsion (mechanics) The twisting of an object due to an applied torque.
 * Torque The rate of change of angular momentum of an object.
