Short description: Overview of and topical guide to 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
  • Multi-Level Bridges
  • Viaduct
  • Vierendeel bridge

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 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 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.
