{{Short description|1=Overview of and topical guide to bridges}}{{unreferenced|date=July 2018}}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. {{TOC limit|limit=2}} What type of thing is bridges? 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
- Cantilever Bridge
- Stressed ribbon bridge
- Arch Bridge
- Tied Arch Bridge
- Through arch bridge
- Skew arch
- Suspension Bridge
- Simple suspension bridge
- Tubular 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

History of bridges History of bridges 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.
